Multi-caret support in Helix is awesome. It’s even the first feature they mention on the homepage.

You can `C` to extend the caret down, or `s` to enter a multiple regex selection. It even keeps your copied/deleted text per caret.

I do wild things with it all the time, like changing a structured document into a completely different structure.

Indeed. Helix's multi-cursor support seems like a rocket-powered chainsaw to me.

It's powerfully expressive. IIRC, you can select a region (such as a whole file), split the selection into multiple cursors, retain only the selections which match a regex, among other things.

What is the equivalent of Sublime's Ctrl + D? Double-clicking to select something, then Ctrl + D to select all instances of that something, while creating multi carets on each.
