Description: A typo in a custom key binding entered via Advanced Key Binding (which is not validated), such as instead of , crashed IDLE at startup: File ".../idlelib/multicall.py", line ..., in bind self.__binders[triplet[1]].bind(triplet, func) ... _tkinter.TclError: bad event type or keysym "up" MultiCall.event_add stores the parsed sequence without validating the keysym, so the TclError is raised later, when a virtual event is bound and MultiCall performs the actual Tk bind. With no window yet, IDLE just exits. Catch TclError at both binder call sites (MultiCall.bind and MultiCall.event_add) and ignore the invalid binding with a warning naming it. The bind path also drops the bad sequence from the virtual event, which avoids a secondary ValueError if it is later rebound or unbound. 🤖 Generated with Claude Code Issue: gh-55646
