"  * Create tags for specific langauges: `let g:campo_custom_ctags_args = '--languages=C,C++,Elixir'

" current project tags and Jai module tags (the latter isn't needed if you
" have Jai module tags in your local file, which can be generated using the
" ctags module at compile time). Related, if you're generating jai ctags and
" the editor isn't finding module references then check if the current
" directory is set to where the tags file exists. I've been caught up by this
" because I have a build.jai in the root and my code in a src/ folder, so the

" will introduce a delay before the mapping is handled in order to wait for
" the entire sequence to be typed. e.g. <leader>s and <leader>sg will
" introduce a timeout delay, which will be noticed when you're trying to use
" <leader>s. If you type <leader>sg then it'll be handled immediately, unless

" You can adjust the timeout duration by modidying the timeoutlen option.

"
" The difference between map and noremap is that the former does recursive
