I agree. I also think F13-16 support should be replaced with Shift F1-12 
support in winio.c. I have a patch that refactors bind key parsing to allow 
combinations of the meta, shift and control modifiers.

A couple lines in keycode_from_string(), support in winio.c (hardest part) and 
F1-12 could use any modifier combo supported by the terminal. In ncurses, 
S-F1-12 is F13-24 and ^F1-12 is F25-36. I don't know about other terminals, but 
urxvt produces unique sequences for F*, ^F*, S-F*, S-^F*, M-F*, M-S-F* and 
M-S-^F*.
