Recently, I posted about my Karabiner-ElementsComplex Modification Rule to map a key to Escape. Here, I make a small tweak to use it to launch an application too!
Here is my list of free, macOS apps that I have installed and use often. Many are also open source! When I first got my Mac I searched the internet for lists of useful apps but found most outdated. I decided to compile this list as part of a cleanup and "audit" of what's useful IMHO.
