Multiple cursors in Scintilla?

[netdude78]

I believe there is some support for multiple cursors in scintilla.  At least I have found some stuff when searching.  Is it possible to get any "vertical editing" capabilities?  Right now I usually just copy code, paste it in VSCode or Sublime Text and then do the multi-edit in there.  Especially since there are cool vertical text editing plugins like "text pastry" for autoincrementing etc.

Thoughts?

// script "Multiple selections in LA.cs"
/// Enables multiple selections in the LA code editor.
/// To auto-enable for each document, add this line in Options -> General -> Run scripts...: Multiple selections in LA.cs
///
/// Does not implement "select all matching words".
/// Scintilla also supports rectangular selections, but this code does not enable it.
/// More info: https://www.scintilla.org/ScintillaDoc.html#MultipleSelectionAndVirtualSpace
///
/// This code is for LA 0.12. In 0.13 will be different.
///
/// The most recent selection is the main selection.
/// Additional selections have thinner caret.
///
/// Ctrl+click - create new empty selection.
/// Ctrl+doubleclick or Ctrl+drag - create new selection.
/// Esc - single selection.
/// When multiple selections are active:
/// - Changing text in one changes text in all.
/// - Pastes in all.
/// - Copies from all without a separator.
