Also want to propose that these v: variables should be settable by the
scripts in case the RHS of a map is a <Mouse> key. E.g., the following
should work (note: it is just indented to show the usage, not
particularly a useful example):
" Make <F12> always <RightMouse> at the center of the current window.
imap <expr> <F12> CenterRightMouse()
function! CenterRightMouse()
let v:mouse_window = winnr()
let v:mouse_line = winheight('.')/2
let v:mouse_col = winwidth('.')/2
return "\<RightMouse>\<RightRelease>"
endfunction
