" Notes:
"
" Keys were chosen not to conflict of to be close to window manager combos
" Like Awesome has a combo (Meta-q) which could be confused with a VIM quit
" mapping (Alt-q).
"
" Other keys were chosen not to conflict with existing VIM functionality
" like Alt-t (OpenNerdTree).
"
" While we could try to map other meta keys like Menu or AltGr, this
" is currently not supported by VIM and could even cause more confusion with
" other applications.
"
" For the quit combo, an approach like listening to VimLeave would work if
" this event would be triggered by the window manager when killing VIM window,
" but this does not seem to be the case. Anyway there's interesting discussion at
" https://stackoverflow.com/questions/5142099/how-to-auto-save-vim-session-on-quit-and-auto-reload-on-start-including-split-wi
"
" Pressing Alt-<key> simultaneously is equivalent to pressing ESC and then <key>,
" so the big difference between the ESC combos and Alt combos are mainly of
" config file notation.
"
" Typing ESC keys combos have the advantage over Alt combos as they are
" difficult to be mistaken for the Meta key, but thats mainly a user and not
" config convention since they're almost the same in VIM.
"
" In the other hand, there's an disadvantage of using ESC simultaneously for
" going to normal mode and doing other stuff, with can be in ambiguous.
"
" The sollution is to decrease ESC timeout.
