Alfred, Karabiner-Elements (for the hyper key functionality), Shortcat, TextSniper, Moom, Sublime Text, iTerm 2, my .bash_profile.
These are all apps for which I have long-standing muscle memory. If I use a new computer, I'm still pressing the keys but nothing happens and I have to remember how to do the things the normal way.
Each of the features provided by the above apps would also require an app to be installed for Windows, too. Not sure how this can be leveled as an OSX criticism.
Never heard of Shortcat before, it reminds me of that vim shortcut that used to be popular for firefox back in the day. I can see how that would be really powerful.
