Smart Shortcuts

s-. — Open the item at Point

In programming modes, this will open the definition/declaration of the item (the function, for instance) — and s-. will take you back to where you came from.

If you’re on a filename or a hyperlink (e.g. in a comment or in a string), it will open that.

If you’re in an Org mode link to a URL or local file, it will open that instead.

s-r — Run the Code

If some code is selected, that will be run. Otherwise the entire buffer will be run by calling the appropriate interpreter/tool.

s-n — Narrow or Widen Intelligently

If you’re in a programming mode, it will narrow to the function.

In Org mode, narrows to the current sub-tree if any.

If invoked from a selection, it will narrow to that selection.

If you’re already narrowed, it will widen automatically.
