I’m a big fan of the Dash documentation tool for macOS. In particular, I often create my own Dash cheat sheets to help me remember commands I frequently forget.
I make enough of these that I created a simple Go app named cheat to generate a skeleton cheat sheet. I also created an UltiSnips snippet to make it easier to generate categories and entries in cheat sheets.
snippet entry "cheatsheet entry"
entry do
name '$1'
notes <<-'END'
\`\`\`
$2
\`\`\`
END
end
endsnippet
snippet category "cheatsheet category"
category do
id '$1'
end
endsnippet
On Neovim, this would go in ~/.config/nvim/UltiSnips/ruby.snippets
