Vim <leader> command works, but beeps error sound and moves the cursor

I have the following configuration in my .vimrc in OSX under MacVim.

let mapleader = ','
nnoremap <leader>af :Autoformat<CR>         " autoformat document
nnoremap <leader>ig :IndentGuidesToggle<CR> " indent guides toggle
nnoremap <leader>nt :NERDTreeToggle<CR>     " nerd tree toggle
nnoremap <leader>tb :TagbarToggle<CR>       " tagbar toggle

The commands work fine, but when I use them, the terminal beeps the sound for error and the cursor moves position about 4 lines. This happens both when using Vim in iTerm2 and in GVim.

Any idea why this is happening and how to fix it?

Solution

  • Do not put comments on the same line as your mappings as the comments will be executed.

    let mapleader = ','
" autoformat document
nnoremap <leader>af :Autoformat<CR>
" indent guides toggle
nnoremap <leader>ig :IndentGuidesToggle<CR>
" nerd tree toggle
nnoremap <leader>nt :NERDTreeToggle<CR>
nnoremap <leader>tb :TagbarToggle<CR>
