I'd like to remap a modified click in gvim (and also MacVim), but certain combinations of modifiers work while others do not. In gvim on a Linux box, I would like to insert "hello" anywhere I type:
:noremap <C-S-LeftMouse> <LeftMouse>ihello<ESC>
However, that command does not work: control-shift-click retains its original behavior. Yet I can remap control-click in gvim:
:noremap <C-LeftMouse> <LeftMouse>ihello<ESC>
In MacVim, command-shift-click <D-S-LeftMouse>
is likewise unresponsive, as are most other modified clicks.
How can I actually remap the modified mouse clicks?
