How to get selected text in Ace editor?

Question

I look through documents, and also select the source code, and I find nothing, all I see are selection and range objects, as well as methods that control ranges.

Answer 1

It is better to use editor.getSelectedText() instead.

Answer 2

Found in the source code of the Ace editor:

 editor.getSession().doc.getTextRange(editor.selection.getRange());
