What is Select All?

Selecting everything in a list or display means choosing all of the text, files, or other items. Ctrl+A selects (highlights) everything in the active window in the majority of apps. For instance, in Microsoft Word, pressing the shortcut keys Ctrl+A selects all of the document's text. Ctrl+A in Explorer selects all discs, files, and folders in the currently open location. Additionally, once everything has been picked, you have the option to remove everything that has been selected or cut and paste the selected items.

How to use your computer, phone, or tablet to choose each and every selectable item on a website or in a window. There are a few alternatives for choosing all text, files, and images on Macs and Windows PCs. You can quickly pick every word you've put onto a page if you're using an iPhone, iPad, or Android device, as well as selectable text on websites and in other apps.

How to Select All

1) On Windows Computers

  • Press Control+A on the keyboard: This quick keyboard shortcut selects anything that can be selected on the current page or window. For instance, you can use this keyboard shortcut to select anything in a Word document, including photos and other objects. This is how it goes:
    • Selecting a window or page is as simple as clicking it.
    • Press Ctrl and A simultaneously.
    • Everything that can be selected is now selected.
  • In applications, select Edit from the menu: There will frequently be a Select all option in an app's Edit menu if you're using that programme. This tool has the same functionality as the Control + A keyboard shortcut, but it is available through a menu.
    • Let's imagine, for illustration, that you are using Notepad to view a text file. To select every character in the text file at once, pick all from the Edit menu by clicking the Edit menu button.
    • Another example is iTunes, where you may pick all of the music that are currently being displayed in the window by selecting Select all from the Edit menu.
    • You cannot utilise select all on the current page or window if it is greyed out.
  • Use the options in Windows File Explorer: You can utilise the menu options in the window's upper-left corner to select all if you're in a File Explorer window, such as one where you're looking through your documents or the This PC folder.
    • The files you want to choose are in the folder that is open.
    • In the window's upper-left corner, click the Home tab.
    • In the "Select" area of the toolbar at the top of the window, click Select all. Currently, the entire panel is chosen.
  • Use the context menu by right-clicking: In many instances, you can Select All from the context menu that appears when you right-click a blank section of a window or webpage. Normally, this will select all of the content on the page, including all of the text, images, and other objects. Or it will choose each file in the window or panel if you're browsing files.

Note: If your mouse doesn't have a right mouse button, you can open the menu by tapping two fingers together on the mouse's touchpad.

    • Say, for illustration, that you are looking at a list of files in a Finder window. To swiftly choose every file in the open folder, select all from the Edit menu by clicking on it.
    • Another illustration is iTunes, where you may pick all of the tracks that are currently visible in the window by selecting Select all from the Edit menu.
    • You cannot utilise select all on the current page or window if it is greyed out.
  • Press the keyboard shortcut Command+A : You may use this rapid keyboard shortcut on practically any window, page, or screen on your Mac to pick everything that's selectable.
