Macintosh Keyboards <TOC>
The second most important use of the keyboard (after inputting data) is executing “keyboard shortcuts”. A keyboard shortcut, also known as a keystroke, is a sequence of keys that activates a command or feature in the frontmost program.
A keystroke is activated by holding down one or more “modifier keys” and then pressing another key, usually a letter. The combination of modifier keys changes (modifies) the function the letter keys on your keyboard.
There are four modifier keys on the Mac keyboard. Their names, markings, and the symbols used to represent them in this Wikibook are listed in the table below.
|Command||⌘, ‰ &#F8FF;||⌘|
Around the Mac OS and in this wikibook, keystrokes are written using shorthand. Modifier keys are represented by the symbols listed in Table 1. “Press the “B” key while holding down Command” is written as “⌘B”. “Press the “B” key while holding down Command and Option simultaneously” is written as “⌘⌥B”.
