What are the F1 through F12 keys?

The F1 through F12 keys are a set of 12 keys located at the top of a computer keyboard. These keys are also known as function keys and have special functions that are determined by the operating system or the active program.

What are the F1 through F12 keys

These functions can vary depending on the context of their usage and the software being used, but commonly include shortcuts for system functions such as opening help menus, controlling audio and video playback, managing open windows, and adjusting settings such as screen brightness and volume. Some of the keys can be used in combination with the Alt or Ctrl keys to perform different actions.

1) F1 Key

The F1 key is a button located at the top of most computer keyboards. It is often used to open the help menu or manual for the operating system or the active program you are currently using. When you press the F1 key, a window or menu with instructions and information on how to use the program will appear. However, the F1 key can also have other functions depending on the computer and the program, such as opening the setup screen or in-game help menu or even pausing the game. The specific function of the F1 key may vary depending on the software or application you are using, so it's best to check the documentation or help files to understand the function of the F1 key.

How To Use F1 Key?

To use the F1 key, you need to open the program or application that utilizes the key. Once the program is open, press the F1 key on your keyboard. This will typically open the help menu or manual for the program.

Some keyboards may have a secondary function for the F1 key, which is indicated by an icon on the key. To use the secondary function of the F1 key, press and hold the Fn key while also pressing the F1 key. The specific secondary function of the F1 key can vary depending on the keyboard and the program, so you may need to consult the documentation or help files to find out what the secondary function is.

On some keyboards, the function keys are the secondary function by default, and you need to press and hold the fn key to access the primary function. For example, on an Apple computer, you need to hold down the fn key and press F1 to access the primary function of the key.

On some keyboards, there is a Function Lock (FnLk) key. When it is enabled, it makes the keyboard act as if the Fn key is being pressed until it is unlocked.

If the F1 key is not working on the keyboard, it could be due to a hardware or software issue. You may need to check for any possible issues with the keyboard, or check the settings or troubleshoot the problem.

Where is the F1 Key Used?

The following is a list of all the places the F1 key can be used.

  1. Open help with all programs
  2. Google Sheets
  3. Microsoft Excel
  4. Microsoft PowerPoint
  1. Open Help with All Programs: Pressing the F1 key while using a program will typically open a help screen or guide within the program. This can provide information on how to use the program's features and functions. In some cases, pressing F1 may also direct you to a helpful webpage on the internet for the program. In the latest versions of Microsoft Windows, pressing the Windows key + F1 will open the Microsoft Windows help and support center, which can provide information and assistance for various issues related to the operating system.
  2. Google Sheets: In Google Sheets, the formula help menu can be expanded and collapsed by clicking on the "f1" button located next to the formula bar at the top of the sheet. This will open a drop-down menu with various formula options, including a list of commonly used formulas and a search bar for more specific formulas. To collapse the menu, click on the "f1" button again or click anywhere outside of the menu.
  3. Microsoft Excel: This shortcut key combination allows you to quickly create a new worksheet tab in the current workbook without having to go through the Ribbon or the right-click menu. When you press Alt+Shift+F1, a new worksheet tab will be added to the right of the current tab and will be named "Sheet2," "Sheet3," etc., depending on how many tabs already exist in the workbook. This can be a useful shortcut for when you need to add multiple worksheets to a workbook or for quickly creating a new tab for a different set of data or calculations.
  4. Microsoft PowerPoint: In all views except Reading View and Slide Show, to open the PowerPoint help menu, you can click on the "Help" button in the top right corner of the PowerPoint window or press the "F1" key on your keyboard. In the Slide Show view, to display a list of shortcuts for use in a slide show, you can press the "F1" key on your keyboard while in the Slide Show view. This will bring up a help menu with a list of shortcuts that can be used during the slide show, such as navigating between slides, activating the laser pointer, and more. You can also press the "Shift + F1" key to bring up a list of shortcuts specifically for the slide show view.

2) F2 Key

The F2 key is a commonly used function key that has many uses across different programs and operating systems. In addition to renaming files and icons in Windows, it can also be used to access BIOS setup, edit cells in Excel, open the open document window in Word, and display the print preview window in Word. It can also have different uses in other programs and applications.

How to Use F2 Key?

To use the F2 key, you will first need to open the program or application that uses the key. Once the program opens, you can press the F2 key to activate its primary function. If the F2 key has an icon on it, it means that it also has a secondary function. To use the secondary function, you will need to press and hold down the "Fn" key, and while holding it down, press the F2 key.

If the F2 key performs a secondary function when you press it, this usually means that the function keys are set as the secondary function. For example, on an Apple computer, you may need to press and hold the "Fn" key and then press the F2 key to activate its primary function.

Where is The F2 Key Used?

The F2 key is used in a variety of programs and applications, including:

  1. Microsoft Windows
  2. Microsoft Excel
  3. Microsoft Word
  4. Notepad++
  1. Microsoft Windows: In Microsoft Windows, the F2 key can be used to rename a selected file or folder quickly. When a file or folder is highlighted or selected, pressing F2 will allow you to type a new name for the file. If multiple files are selected, and you press F2 to rename one of them, all of the selected files will take on the new name, with a number added to the end of each file name to distinguish them. For example, if you had three files selected and you renamed one of them to "test," all three files will be renamed to "test (1)," "test (2)," and "test (3)."
  2. Microsoft Excel: In Microsoft Excel, the F2 key can quickly edit an active cell’s contents. To use this feature, navigate to the cell you want to edit using the arrow keys. Once the cell is highlighted, press F2 to enter into the editing mode, and you can then add, delete or change the text in the cell. The changes will be saved automatically when you press enter or move to another cell. This function is handy when you need to make quick changes to a specific cell without having to use the mouse to double-click on the cell.
  3. Microsoft Word: In Microsoft Word, the combination of keys Ctrl+F2 can be used to display the print preview window quickly. This will allow you to see how the document will look when printed and make any necessary adjustments before actually printing. The combination of keys Alt+Ctrl+F2 can be used to open the open document window in Microsoft Word. This will display a window that allows you to browse and select a document that you want to open in Word. This is a useful feature when you want to open a document that is not currently open in Word or when you want to switch between multiple open documents quickly.
  4. Notepad++: In Notepad++, the combination of keys Ctrl+F2 can be used to create a bookmark on a specific line in a file. Bookmarks are useful for quickly navigating to specific lines or sections of a file, especially in large files where it can be not easy to find a specific piece of information.

The key F2 can be used to cycle through the available bookmarks in a file. When you press F2, Notepad++ will take you to the next bookmark in the file, making it easy to move between different sections of a file. This is useful when you are working with large files, and you need to jump between multiple specific lines or sections.

3) F3 Key

The F3 key is a function key that is often used to open the find or search feature of a program or operating system. However, its specific use can vary depending on the program or operating system being used.

How To Use F3 Key?

To use the primary function of the F3 key, press the F3 key while in the appropriate program. If the F3 key also has an icon on it, it may indicate that it has a secondary function. To access the secondary function, press and hold the Fn key while also pressing the F3 key. The specific secondary function of the F3 key can vary depending on the program or operating system being used.

It's also worth noting that on some keyboards, the function keys may have enabled function lock, which means that the keyboard will act as if the Fn key is being pressed until it is unlocked.

If the F3 key is not working on the keyboard, it may be due to a hardware issue or a software conflict. You can check the troubleshooting steps for resolving the issue, such as checking the keyboard settings, checking for any stuck keys, or updating the keyboard driver.

Where is the F3 Key Used?

The F3 key is used in many programs and operating systems, and its specific use can vary depending on the program or operating system being used.

Some common uses of the F3 key include:

  1. Apple macOS X
  2. Microsoft Excel
  3. Windows Explorer
  4. Microsoft Outlook
  5. Microsoft Word
  6. Microsoft Windows
  7. Windows command line

1. Apple macOS X: On an Apple computer running the macOS X operating system, pressing the F3 key opens Mission Control, which allows you to view all open windows and switch between them. Mission Control also shows you all open spaces, which are virtual desktops you can use to organize your windows. It also provides an overview of all the open apps and windows and allows you to switch between them quickly.

2. Microsoft Excel: F3 is a keyboard shortcut in Microsoft Excel that is used to paste names. When you press F3, any names that have been previously defined using the "Define Name" feature will be displayed in a dialog box. You can then select the name you want to paste and press OK. This will insert the named range into the current cell or selected cells.

3. Windows Explorer: The F3 key can be used to open the search tab in Windows Explorer, allowing you to search for files and folders on your computer. Once you have opened Windows Explorer, press the F3 key to bring up the search bar. You can then enter your search terms and press enter to begin the search.

4. Microsoft Outlook: In Microsoft Outlook, pressing the Windows key+F3 keyboard shortcut will open the Advanced Find window, allowing you to search for specific emails or other items in your mailbox. The Advanced Find feature provides more options and filters than the basic search function, making it a useful tool for locating specific items within your mailbox.

5. Microsoft Word: In Microsoft Word, the shortcut Ctrl+F3 will lowercase any highlighted text, and Shift+F3 will change the case of the text from upper to lowercase or a capital letter at the beginning of every word.

6. Microsoft Windows: In Microsoft Windows 7 and earlier, pressing F3 on the Windows desktop opens a window to find files. However, in Windows 10, the F3 button no longer has any function on the desktop.

It is worth noting that, in Windows 10, you can use the search function to find files or use the file explorer to look for files.

7. Windows command line: In MS-DOS or Windows command line, pressing the F3 key will repeat the last command that was entered. This can be a quick and easy way to re-run a command without having to type it out again.

4) F4 Key

The F4 key is located at the top of most computer keyboards and is a function key that typically has multiple uses depending on the context. It is often used in combination with the Alt and Ctrl keys to perform specific actions such as closing open windows and tabs. However, the specific functions of the F4 key can vary depending on the computer and program in use. Some programs may use F4 as a shortcut key for a specific function, while others may not use it at all. It is best to consult the documentation or manual of the specific program or operating system in use to understand the functions of the F4 key.

How To Use F4 Key?

To use the F4 key, open the program or application that uses it and press F4. If the F4 key has a secondary function, it will typically be indicated by an icon on the key or in the program's documentation. To use the secondary function, press and hold down the Fn key (located near the bottom-left corner of the keyboard) and press F4 while holding the Fn key.

On some computers, the function keys (F1, F2, F3, etc.) are the secondary function, so pressing Fn+F4 will activate the F4 key.

If the FnLk (function lock) is enabled, the keyboard will act as if the Fn key is pressed, even if you're not holding it. So, all the function keys will act as their secondary functions. To disable this, you can press the Fn+FnLk key (This key is typically located on the keyboard)

If the F4 key is not working on the keyboard, it could be caused by a software issue or a hardware problem with the keyboard. You can try troubleshooting by checking for updates to the program or application you're using or by checking for any issues with the keyboard driver. If that doesn't help, try connecting an external keyboard to the computer and see if the F4 key works on it. If the problem persists, it may be best to seek technical assistance.

Where is F4 Key Used?

The F4 key can be used in a variety of programs and applications, including:

  1. Microsoft Excel
  2. Microsoft PowerPoint
  3. Microsoft Windows
  4. Microsoft Word
  5. Microsoft Internet Explorer

1. Microsoft Excel: In Excel, cell references are used to refer to specific cells or groups of cells in a worksheet. When writing a formula, you can choose whether to use an absolute or relative cell reference. An absolute cell reference stays the same, even when the formula is copied to a different cell. A relative cell reference changes based on the position of the formula in the worksheet.

Pressing F4 while in the formula box allows you to switch between different reference types quickly. For example, you can switch a relative reference to an absolute reference by pressing F4 and vice versa. This helps to make the process of creating formulas more efficient and convenient.

2. Microsoft PowerPoint: In Microsoft PowerPoint, pressing the "F4" key repeatedly will cycle through the different repeat options for the last action performed. This allows you to quickly repeat an action with different options, such as different cell ranges in Excel or different slides in PowerPoint. For example, if you insert a shape and press "F4", it will repeat the insertion on the same slide, then repeat the insertion on all slides, then turn off the repeat function.

3. Microsoft Windows: The combination of Alt + F4 is commonly used to close the currently active window in Microsoft Windows, while Ctrl + F4 is used to close the active tab or window within a program. In older versions of Windows, such as Windows 95 to Windows XP, the F4 key was used to open the Find window for searching for specific files or text within a program.

4. Microsoft Word: In Microsoft Word 2000 and later versions, the "F4" key is used to repeat the last action performed. This can be a time-saving feature, as it allows you to quickly repeat formatting changes, insertions, deletions, and other actions without having to perform the steps again manually. This can be especially useful for repetitive tasks, such as applying the same formatting to multiple text sections.

5. Microsoft Internet Explorer: In Microsoft Internet Explorer, the "F4" key can be used to open the "Address bar," where you can type in the URL or search term to navigate to a new web page. It can also be used to cycle through the open tabs in the browser, making it easier to switch between multiple tabs without using the mouse. When the "Address bar" is open, pressing "F4" repeatedly will cycle through the history of previously visited websites.

5) F5 Key

In addition to refreshing a web page, the F5 key can also be used for other purposes depending on the software. It can serve as a shortcut for reloading, running a presentation, or opening the "Find and Replace" feature in some text editors. The specific use of the F5 key can vary by program and operating system, so it's best to consult the software's documentation for more information.

How To Use F5 Key?

To use the F5 key, open the program that uses it and press the key. If the program requires the use of the secondary function, press and hold the Fn key and then press F5. If the FnLk (function lock) is enabled, you may need to unlock it in order to use the function keys. If the F5 key is not working, it could be due to a hardware issue or a software conflict, and you may need to troubleshoot the problem by checking the keyboard and drivers.

Where is F5 Key Used?

The F5 key is used in many different programs, including:

  1. Internet browser
  2. Microsoft Excel
  3. Microsoft Windows
  4. Microsoft Word
  5. PowerPoint

1. Internet Browser: The F5 key is commonly used in Internet browsers to refresh or reload the page or document window. Pressing Ctrl+F5 forces a complete refresh of the web page, downloading all its contents again, including any images or other resources that may have been cached. This can be useful if you need help viewing updated content on a web page or if the page needs to display correctly.

2. Microsoft Excel: In Microsoft Excel, pressing F5 displays the "Go To" dialog box, which allows you to navigate to a specific cell, range, or defined name in your worksheet. Ctrl+F5 restores the window size of the selected workbook window, which can be useful if the window has been resized or maximized. This can be helpful for adjusting the window size to better view your data or for comparing data in different windows.

3. Microsoft Windows: In Microsoft Windows, pressing F5 in File Explorer refreshes the list of contents in the current folder, which can be useful if you've added, deleted, or renamed files or folders and need to update the view. This can also be useful if you're troubleshooting a problem with your files and need to see the latest changes. The F5 key is a quick way to refresh the view in File Explorer without having to navigate away from the current folder and then back again.

4. Microsoft Word: In Microsoft Word, pressing F5 opens the "Find and Replace" dialog box, which allows you to search for and replace specific text in your document. You can use this feature to make changes to your document quickly or to correct errors. The "Find and Replace" dialog box also has options for specifying search criteria, such as a matching case or whole words only, and for replacing all occurrences of the search text or just selected occurrences. This feature can save time and effort when making changes to a long or complex document.

5. PowerPoint: In Microsoft PowerPoint, pressing F5 starts a slide show from the first slide. This can be useful if you want to view your presentation from the beginning or if you've made changes to the beginning of your presentation and want to review them. Pressing Shift+F5 starts the slide show from the currently active slide, which can be useful if you're reviewing or practicing a specific section of your presentation. You can use the slide show view to preview how your presentation will look when you give it to an audience and make any necessary adjustments to the content, timing, and transitions.

6) F6 Key

Its primary purpose is to move the text cursor to the address bar in an Internet browser, allowing you to quickly enter or modify the URL of the web page you want to visit. However, the specific use of the F6 key can vary depending on the program and operating system being used. In some programs, the F6 key may have a different function, such as changing the screen or window focus or moving between different elements of the user interface. It's important to consult the documentation for the specific program or operating system you're using to determine the exact behavior of the F6 key.

How To Use F6 Key?

The F6 key is used differently depending on the program being used. To use the primary function of the F6 key, press the key. If the F6 key has a secondary function, it can be accessed by holding down the Fn key and pressing F6. If the FnLk (function lock) is enabled, the keyboard will act as if the Fn key is always being pressed until it is unlocked. The specific secondary function of the F6 key can vary. The program's documentation usually finds information on its secondary function. If the F6 key is not working, the issue could be with the keyboard or the program and should be investigated.

Where is F6 Key Used?

The F6 key can be used in various programs and applications. Some of the most common ones include:
