What is a key Combination?

A key combination, also known as a keyboard shortcut, is the simultaneous or sequential pressing of multiple keys on a keyboard to produce a specific outcome. These combinations often perform various actions in the operating system or a program, such as copying text or opening a new window. These shortcuts can help save time when working with documents or other tasks.

Key combinations vary depending on the operating system and program being used. For example, in the Windows operating system, the key combination "Ctrl + C" is used to copy selected text or an image, while in macOS, it is "Command + C". Similarly, "Ctrl + Alt + Del" is used to open the task manager in Windows. At the same time, in MacOS, it is "Command + Option + Esc".

Many programs also have their own shortcuts, which can be found in the program's documentation or the "Help" menu. Additionally, key combinations are often denoted with a "+" sign between the names of the keys pressed when written. For example, "Ctrl + C" would be written as "Ctrl + C" instead of "Ctrl-C".

Key combinations are a useful tool for quickly performing actions on your computer. They can help save time and make your work more efficient. It's worth learning the most commonly used key combinations for the operating system and programs you use most frequently.
