Answer «it can't» is false. While there is no possible system-independent
solutions in pure vimscript, system-dependent and/or not pure vimscript
solutions are possible: on linux (and any other system that uses X server), for
example, you can invoke `xset q' (if xset is installed) and parse its output to
get CapsLock state; maybe there is also some `file' in /proc or /sys which can
be used for this purpose (I don't know for sure) (if it is, then you could write
faster pure vimscript system-dependent solution). It also is not impossible that
some python/perl/ruby/lua/... package contains cross-platform function
getCapsLockState.
You should seek appropriate solution in this direction.
