Mappings

Add map statements to ~/.vimrc. There are special notations for example the <leader>-key which can be custom set.

map ,t :CtrlP

This maps keys <,> to command CtrlP (which is the advanced Command-T command known from browsing files in TextMate/Sublime)

Tips & Tricks

Copy to Clipboard

tmux save-buffer -|pbcopy

I believe the last line from .vimrc should be:

filetype plugin indent on

Thanks, @dmgolembiowski! Made the suggested change. I've not updated this for some time and I switched to using tmux, neovim and asdf. Albeit, I'll probably give Visual Studio Code with some vim-bindings a try next but my coding skills have become a bit rusty.
