I'm trying to set up the NERDComment plugin in vim, but I'm having some trouble with the keys. I'd like to set the basic toggle functionality (comment a line if it's uncommented, uncomment if it's commented) to be c. The problem is that I've remapped the Leader to be ,, which is the same key that NERD wants for all of it's hotkeys. Anyone have any idea as to how to set this up?
