Question

I know this may be a newbie question but I can’t seem to find it, or make it work.

How do I remap the default keybindings for help files? Basically instead of <C-]> to go forward I would like to use <C-right>, or use <C-left> instead of <C-t> etc. Just make it easier to remember.

Of course this should only change if the file is a help file, otherwise it should not make these changes, so that it doesn’t conflict with anything.

Thanks for all your help! (Also in the past.)

You can use <C-Right> / <C-Left> only in help files if you define the following:

" In ~/.vim/ftplugin/help.vim
nnoremap <buffer> <C-Right> <C-]>
nnoremap <buffer> <C-Left>  <C-t>

" Or in ~/.vimrc
augroup HelpMaps
    autocmd!
    autocmd FileType help :nnoremap <buffer> <C-Right> <C-]>
    autocmd FileType help :nnoremap <buffer> <C-Left>  <C-t>
augroup END

Although I do not think it is a tiny bit useful to do so only in help buffers. Such mappings will not possibly interfere with anything but plugins defining their own <C-Right>/<C-Left> mappings.
