Vim gets its key in "cooked" mode. Even gvim, which can distinguish
its keys and chords a little more subtly than Console Vim can, gets
its key in a rather standard manner. This means that keys other than
Shift, Ctrl, Alt, and, on the Mac, Cmd, cannot be used as key
modifiers; conversely, the key modifiers just named cannot be used
_except_ as key modifiers. If you hit i and k at the same time, then
depending on which one of them was got by the keyboard a minuscule
fraction of a second before or after the other, you'll get either ik
(start Insert mode and insert the letter k or whatever is langmapped
to it) or ki (move one line up then start Insert mode). You may set a
multicharacter {lhs} in a mapping, but even then, with the example you
give, you'd get either "он" (which, in Russian, would conflict with
e.g. the personal pronoun meaning "he") or "но" (which would conflict
with the conjunction meaning "but"). A mapping triggered by the one
would not recognize the other.
Most of the "printing" keys already have a function: in Insert mode
they of course insert a character into the text, and even in Normal
mode, the unassigned printing keys are few and far between. The same
applies to the "control" chords of these printing characters, of which
only Ctrl-A to Ctrl-Z (which are the same as Ctrl-a to Ctrl-z), plus
Ctrl-@ (Null), Ctrl-[ (Escape), Ctrl-\, Ctrl-], Ctrl-^, Ctrl-_ and
Ctrl-? (the only ones which have a representation in ASCII) can be
sensed by Vim. For this reason, I recommend to concentrate on the F
keys (with or without Shift, and with the exception of F1 = Help and
F10 = Menu) for the {lhs} of mappings, except when the intentionally
replacing an existing binding with a similar but slightly different
function, e.g. with
map j gj
map k gk
to move up or down by screen lines with j and k, leaving <Up> and
<Down> to move by file lines.
Best regards,
Tony.
