I will next time I’m in a theater that is on fire.

You in fact can yell fire in a theater without being arrested. It depends on the context (and weather or not there where injuries)

If the play calls for it and an actor says it. Or more simply if the theater is on fire.

With speech laws it matters more what the context is to the intended audience than what is specifically said.

And once you’ve got those Keybindings in there they never leave. You just start typing expecting them to always work.
