How do I disable a a key in Tagbar

Question

I've mapped 'L' and 'H' to change buffers in vim. I often end up hitting these keys in NERDTree and Tagbar.

I'm able to use NERDTreeAddKeyMap to make NERDTree ignore keys. Tagbar only allows the use of g:tagbar_map_.* to replace key bindings that exist.

Is there a way I can make 'H' and 'L' do nothing in the Tagbar?

Answer 1

You can use a FileType autocmd and map those keys to <Nop>:

augroup TagBar
    autocmd!
    autocmd FileType tagbar nnoremap <buffer> H <Nop>
    autocmd FileType tagbar nnoremap <buffer> L <Nop>
augroup END

Also always remember to enclose your autocmds with a augroup.

Answer 2

You can easily do this with <buffer>-specific mappings. Like this:

autocmd FileType tagbar nmap <buffer>H <Nop>
autocmd FileType tagbar nmap <buffer>L <Nop>
