Karabiner – Easy Keyboard Remapping for OS X
This application has been really huge for my productivity.I have literally rebinded every single key on my mac with it. It is very powerful especially when you combine it with the multitude of Alfred workflows and different scripts that you can run.I open Alfred with just single press of right command, I switch between all my apps through hotkeys, my caps lock is a hyper key, my right shift is delete. Can't give more praise to this tool really.Here is how I use it and what my config file for it looks like for all interested :https://github.com/nikitavoloboev/dotfiles/tree/master/karab...More importantly, it allows to keep myself sane with the enormous amounts of apps and tools I run on my system (https://github.com/nikitavoloboev/my-mac-os) and interchange with them seamlessly.
