How do I configure the Emacs-like keyboard shortcuts in OS X? OS X has built in support for many Emacs-like keyboard shortcuts: for example, Control-A moves the cursor to the beginning of the paragraph and Control-E moves the cursor to the end. How can I configure these shortcuts and add more of them?
Here are some good resources on how to add and configure these keyboard shortcuts:


A detailed exploration of these shortcuts by Llew Mason, unfortunately only available now through the Wayback Machine.
A similar article by an anonymous author (I think) that includes some caveats about specific methods.
A GitHub repository by Brett Terpstra that shows examples of some relatively complex key bindings.
A deep dive into the Cocoa Text System by Jacob Rus. It’s a decade old now but I’m guessing that a lot of the information is still applicable to today’s macOS.
