10.4.1 Special Keys
A more complicated keyboard customization task is binding commands to special keys, such as arrow, numeric keypad, or function keys, on your keyboard. This level of customization takes some work, but if you like using special keys, it is well worth the effort.
Most of the special keys have reasonable names, but using them with the set key functions discussed above requires using a slightly different syntax. The name of the key appears inside square brackets rather than inside double quotes. For example, you could bind the goto-line command to the function key F5 like this:
(global-set-key [f5] 'goto-line)
And you can certainly use modifiers with your special keys. Control-Alt-F5 can be bound like this:
(global-set-key [C-A-f5] 'goto-line)
Table 10-3 lists the names of some common special keys.
