patch 9.1.0058: Cannot map Super Keys in GTK UI Commit: https://github.com/vim/vim/commit/92e90a1e102825aa9149262cacfc991264db05df Author: Casey Tucker <dctucker@hotmail.com> Date: Thu Jan 25 22:44:00 2024 +0100 patch 9.1.0058: Cannot map Super Keys in GTK UI Problem: Cannot map Super Keys in GTK UI (Casey Tucker) Solution: Enable Super Key mappings in GTK using <D-Key> (Casey Tucker) As a developer who works in both Mac and Linux using the same keyboard, it can be frustrating having to remember different key combinations or having to rely on system utilities to remap keys. This change allows `<D-z>` `<D-x>` `<D-c>` `<D-v>` etc. to be recognized by the `map` commands, along with the `<D-S-...>` shifted variants. ```vimrc if has('gui_gtk') nnoremap <D-z> u nnoremap <D-S-Z> <C-r> vnoremap <D-x> "+d vnoremap <D-c> "+y cnoremap <D-v> <C-R>+ inoremap <D-v> <C-o>"+gP nnoremap <D-v> "+P vnoremap <D-v> "-d"+P nnoremap <D-s> :w<CR> inoremap <D-s> <C-o>:w<CR> nnoremap <D-w> :q<CR> nnoremap <D-q> :qa<CR> nnoremap <D-t> :tabe<CR> nnoremap <D-S-T> :vs#<CR><C-w>T nnoremap <D-a> ggVG vnoremap <D-a> <ESC>ggVG inoremap <D-a> <ESC>ggVG nnoremap <D-f> / nnoremap <D-g> n nnoremap <D-S-G> N vnoremap <D-x> "+x endif ``` closes: #12698 Signed-off-by: Casey Tucker <dctucker@hotmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
