In computing, a keyboard shortcut (also hotkey/hot key or key binding) [1] is a software-based assignment of an action to one or more keys on a computer keyboard. Most operating systems and applications come with a default set of keyboard shortcuts , some of which may be modified by the user in the settings .
Select all in focused control or window Ctrl+A: ⌘ Cmd+A: Ctrl+A: Ctrl+x, then h: ggVG, unlikely ever needed as most commands take an optional range parameter. % means "all in focused windows" here so e.g. to copy all the text, use:%y: Ctrl+A: Cycle through installed keyboard languages / input methods
Keyboard shortcuts make it easier and quicker to perform some simple tasks in your AOL Mail. Access all shortcuts by pressing shift+? on your keyboard.. All shortcuts are formatted for Windows computers, but most will work on a Mac by substituting Cmd for Ctrl or Option for Alt.
Keyboard keys can also be remapped and disabled—for example, so that pressing Ctrl+M produces an em dash in the active window. [9] AutoHotkey also allows "hotstrings" that automatically replace certain text as it is typed, such as assigning the string "btw" to produce the text "by the way", or the text "%o" to produce "percentage of".

Macro key on an old keyboard. A macro key is a keyboard key that can be configured to perform custom, user-defined behavior. Many keyboards do not have a macro key, but some have one or more. Some consider a macro key to enhance productivity by allowing them to do operations via a single key press that otherwise requires slower or multiple UI ...
An access key allows a computer user to immediately jump to a specific part of a web page via the keyboard. On Wikipedia, access keys allow you to do a lot more—protect a page, show page history, publish your changes, show preview text, and so on. See the next section for the full list.
This was the approach taken by the STAGE2 Mobile Programming System, which used a rudimentary macro compiler (called SIMCMP) to map the specific instruction set of a given computer into machine-independent macros. Applications (notably compilers) written in these machine-independent macros can then be run without change on any computer equipped ...
This is where the most common key sequences have been studied [citation needed], and keys in the same common sequence are placed in the electrical switch matrix such that three keys down cannot produce a fourth "phantom" key by shorting out the matrix. The simplest way to accomplish this is to put all keys in the same common sequence on the ...
