I'm new to Vim and currently having issues with my Leader key in MacVim on OSX 10.7, freshly installed.
I've tried remapping the Leader key to ",", using
let mapleader=","
(in my .vimrc file, at its very top), increased the timeout (to 10000ms). I also activated
set showcmd
To see if it, at all, fires - but it doesnt.
:verbose map ,
does, interestingly, report "no mapping found".
