In addition to Salman's comment, the escape version will also convert
REPLACE mode to INSERT mode.

If you're adamant about using the escape version, I'd suggest using "gi"
instead of "i". This will rid you of the incorrect cursor placement at
the beginning or end-of-line. As in,

   :inoremap <Fx> <Esc>[code]gi

See :help gi.

By the way, can "gi" be made to remember REPLACE mode too? Any opinions,
Bram/developers?
