Most keypad keys have two editing functions associated with them, which means each key has two functions, similar to upper and lower cases on typewriters or function keys on calculators. To use the upper or primary function, only one keystroke is required. To use the lower or alternate function, two keystrokes are required, the Gold,key and then a function key. The Gold key acts as a sluft on a typewriter to create the upper case. During full-screen mode, the editor is driven completely in insert mode.
