38 * Enable (or disable) ncurses' interpretation of a keycode by adding (or
39 * removing) the corresponding 'tries' entry.
41 * Do this by storing a second tree of tries, which records the disabled keys.
42 * The simplest way to copy is to make a function that returns the string (with
43 * nulls set to 0200), then use that to reinsert the string into the
