So you may have seen my KeyBindings project before. It’s an insanely large collection of keybinding tricks that work in any macOS text field. Well, any native cocoa field. You won’t have much luck in Electron or other non-native text editors. But for most uses, including in Safari, Mail, Notes, nvUltra, and most of the Markdown editors, the tricks work great. You can do things like adding TextMate-style ⌘⏎ to any editor to create a new line no matter where your caret (cursor) is in the line.
