! Key Strings
Key strings are made up of zero or more of the modifiers ''alt'', ''shift'' or ''ctrl'' followed by the name of a key, all joined with "+" plus symbols. Key names are either the letter or digit printed on the key (eg "a" or "1"), or one of the special keys ''backspace'', ''tab'', ''enter'' or ''escape''.
