I want to map my F2 for nerdtree with the following entry:
map <F2> :NERDTreeToggle<CR>
But even before that, and after saving the vimrc , whenever i press F2, it just switches the case of the letters on which the cursor is present. Later found out that any function key does it. F5 switches case of 5 characters and so on. Is this because of some other plugin? I presently use c.vim , snippetsEmu , surround , nerdtree , and minibufexpl
There are no keymappings to any function key in my vimrc.
