HUH?
I just accidentally clicked one of those buttons - which are tiny and no text (only a tooltip)…
…and it replaced a bunch of items with… nothing. No undo that I could find, Ctrl+Z doesn’t work. Completely messed up a script.
And where’s “Match whole word”?
This is not an improvement over EditPythonScript. The only thing that is good about this function in ScriptEditor is it tells you the line numbers where the matches are found.
