Sorry, something went wrong.
…-152747) A typo in a key binding, such as <Alt-Key-up> for <Alt-Key-Up>, crashed IDLE at startup. It is now ignored with a warning. On macOS an invalid binding such as <Alt-Key-up> is not parsed into a MultiCall triplet, so it falls back to Tk's event_add(), which was left unguarded and still crashed. Guard the fallback too, and test both the parsed (bind()) and unparsed (event_add()) paths on every platform. --------- (cherry picked from commit b954645) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com> Co-authored-by: Terry Jan Reedy <tjreedy@udel.edu> Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
