Feature request: multi-cursor text selection (Sublime Text style)

[mossr]

This may be a big ask 🙃

I'm a huge Sublime Text fan and my programming productivity relies heavily on multi-cursor selection using ctrl+d:

Most text editors and IDEs (e.g., VSCode) implement this feature. It would be a tremendous help to have this feature within a Pluto cell!

Current alternatives:

• Chrome extension for multi-cursor selection (but doesn't work in Pluto)
• GhostText Chrome extension allows you to mirror a textbox from Chrome to Sublime Text (but this workflow is tedious)

This may be related to #1545 (but that assumes the text is aligned vertically, like the example GIFs I showed above—but imagine we want to change the sum text to something else, rectangular selection wouldn't work here).

Seems like the mechanism for multiple cursors is somewhat in place—again, I understand this is a big ask :)
