I post this here because I don't know where else to ask for a feature.
Please add new line shortcuts for source editing! For example, in Visual Studio Code, you can press Ctrl+Enter to create a new line below where the cursor is, or Ctrl+Shift+Enter to create one above. This is so much easier than going up/down, then pressing End, then Enter.
I don’t know if that one would make it into my personal pantheon of shortcut-worthy editing maneuvers, but I can definitely see how once you’ve had a taste of it, it could be hard to go back to the two-step version.
