In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software.. Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other.
Mac: The classic Mac OS supported system extensions known generally as FKEYS which could be installed in the System file and could be accessed with a Command-Shift-(number) keystroke combination (Command-Shift-3 was the screen capture function included with the system, and was installed as an FKEY); however, early Macintosh keyboards did not support numbered function keys in the normal sense.
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.

Map is sometimes generalized to accept dyadic (2-argument) functions that can apply a user-supplied function to corresponding elements from two lists. Some languages use special names for this, such as map2 or zipWith. Languages using explicit variadic functions may have versions of map with variable arity to support variable-arity functions ...
