A key or combination of keys that execute a specific function or command within an application or operating system. For example, the F7 key in Microsoft Word and other Microsoft programs is the shortcut key for the Spell Checker. If a shortcut has multiple keys, it will be written with all keys required to perform the function. For example, Shift+F7 (pressing and holding the Shift key while pressing the F7 key) opens a thesaurus in Microsoft Word.
Tip: Shortcut keys are not case sensitive. Which means when we list a shortcut key, such as Ctrl + A to highlight all text, it is not necessary to have a capital A.
