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?

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.

  • "I used nmap here instead of nnoremap, because <Nop> cannot be remapped." Use non-recursive mappings by default. Only use recursive ones when you really need them (which is not the case here.) Get into the habit of always using non-recursive mappings. See also excellent advice here: learnvimscriptthehardway.stevelosh.com/chapters/…

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>

    Any reason not to use nnoremap?

  • @D.BenKnoble I believe <Nop> cannot be remapped, so there's absolutely no reason to use nnoremap.
