I have the following keymappings in my vimrc
nmap :Q<CR> :q<CR>
nmap :W<CR> :w<CR>
nmap :WQ<CR> :wq<CR>
However, they do nothing. Vim complains that Q isn't a valid command. Same for W and WQ. I restarted vim and everything. I'm trying to figure this out and I'm also hoping to map Ctrl+W and the arrow keys to just Ctrl+h for changing windows left and etc. How can I go about doing that?
