29 * ex_map -- :map[!] [input] [replacement]
30 * Map a key/string or display mapped keys.
33 * Historic vi maps were fairly bizarre, and likely to differ in
34 * very subtle and strange ways from this implementation. Two
35 * things worth noting are that vi would often hang or drop core
36 * if the map was strange enough (ex: map X "xy$@x^V), or, simply
37 * not work. One trick worth remembering is that if you put a
38 * mark at the start of the map, e.g. map X mx"xy ...), or if you
39 * put the map in a .exrc file, things would often work much better.
