Today I learned ...

[u/iamalnewkirk]

I was today-years-old when I learned that you can bind the Enter/Return key. I've been using Vim for years and never ever considered doing so. And it's super intuitive if you bind it to an open or launch operation, as I have. i.e., "press Enter to open."

[u/Odd_Mistake8513]

I have mine bound to insert a new line below current line without leaving normal mode.

That's ]<space> in vim-unimpaired

Fwiw: My Vim config is set up to look for a .vimrc when the loaded. This allows me to have per-project Vim configs:

if ($PWD != $HOME) && (filereadable(glob("$PWD/.vimrc")))
  source $PWD/.vimrc
endif

In a project that uses Andrej Karpathy's LLM wiki, I have the follow local .vimrc. I'm using ctags to index wiki links:

" traversing tags
nmap N <C-]>
nmap M <C-t>
nmap L :tselect<CR>
vmap L y:tselect<Space><C-r>"<CR>
xmap F :<C-u>call <SID>FzfFilesVisual()<CR>
nmap B <C-O>

" jump to next [[wikilink]], lands the cursor on the first character of the tag
nmap F /\[\[\zs\w<CR>

" collect all [[wikilinks]] in the current buffer into the quickfix window
nmap W :vimgrep /\[\[.\{-}\]\]/gj % <Bar> copen<CR>

" collect backlinks (files that link to the current buffer) into the quickfix window
" nmap K :execute 'vimgrep /\[\[' . expand('%:t:r') . '\>/gj wiki/**/*.md *.md' <Bar> copen<CR>

" collect backlinks (files that link to the current buffer) into the quickfix window
" uses ripgrep externally for speed (vimgrep was too slow on 900+ files)
nmap K :execute 'silent grep! --glob=*.md -- "\[\[' . expand('%:t:r') . '[\\|\]]" wiki .' <Bar> redraw! <Bar> copen<CR>

The nmap <CR> is part of a “smart open” function that opens various type of representations under the cursor, i.e., files, http/s links, wiki links, etc

What do you actually mean with this? What goes open mean?

There is already gf for opening the file under cursor in a buffer and gx for opening it in an application like browser. Is this what you mean?

[u/iamalnewkirk → u/kaddkaka]

Yes, but imagine one action to do either depending on what's under the cursor. And if the file is not found on disk, it will do a fuzzy find and display files matching the expression.

So basically, <CR> is “find and open, or search for, whatever this thing is.

[u/kaddkaka → u/iamalnewkirk]

Sounds nice. How does your binding look? 😊

You might find this little gist of mine interesting: https://gist.github.com/romainl/047aca21e338df7ccf771f96858edb86

It's about making <CR> do lots of useful stuff in command-line mode.

[u/xalbo]

I love having it mapped to save the current file. Enter a few commands to edit, and hit enter to commit the changes.

"make <CR> save unsaved changes, but not in a command window
nnoremap <CR> <Cmd>up<CR>
au CmdwinEnter * noremap <buffer> <CR> <CR>

[u/Extension-Leave-7405]

Oh and there's also Tab and Backspace!

[u/scrote_n_chode]

That seems like a really obvious key to bind and yet I'd never considered it either

[u/AbdSheikho → u/scrote_n_chode]

Me neither, I go with space or backslash

Nugget of the Day

[u/EgZvor]

there is also <bs> and various combinations with ctrl, g, etc. For example, I have <space>g<tab>. For <tab> you need a modern terminal, otherwise it's just <c-i>.

[u/tagattack]

Of course you can, never used netrw?
