Vim has the concept of <cword> and <cWord> (you can :h <cword> these for more info), which are basically the things that vim will jump across when you press 'w' or 'W'. You can combine this with grep and the location list to find symbol usage across multiple files. nnoremap <leader>g :grep <cword><CR> You can then use :cnext and :cprev (or focusing the window and selecting an entry) to navigate between them. As others have stated, you can also use ctags (plugins like https://github.com/ludovicchabant/vim-gutentags are useful for refreshing tags in a project), but for some languages you may need to add a tag definition (e.g. for something like rust or zig). For older languages like C you should be fine.

1) I just use fugitive[0] for that. `git status` in vim is now just the `:G`, command, though I map it to `gs` so it's even quicker. 2) I can't really help you there, at least not in vanilla vim. I make heavy use of tmux and never work on my more than one repo in the same vim instance, nor is my vim's current working directory every anything other than the root of the repo I'm in. So if I do need to open a file in another repo and want to see two repos side-by-side (which is rare but it happens), I make a tmux split. 3) gutentags [1] can help with this. Though nothing is better than using a language server for your given language. That said, I still just have gutentags and mostly just grep/search for `def func` like you currently do.

I am not sure "proof" is the appropriate word. > Dumb Jump uses The Silver Searcher ag (and falls back to grep) ... [and] a set of regular expressions If you're going to install ag, you might as well install universal-ctags[1], a revival of ctags with many improved and new parsers. It allowed me to discard my C and javascript ctags config entirely. Combined with gutentags[2] you have a "just works" and "Less Dumb" setup.

Not exactly similar but https://github.com/ludovicchabant/vim-gutentags is pretty great.
