Directions on how to change "ESC" key from stopping play world (PIE/SIE) w/ screenshots

Edit: Before I found the setting mentioned by OP and thought it was hard-coded, I found out you can bind to the FBindingContext::CommandsChanged event and override it there. You need to make sure this happens early enough, since it’ll only trigger once at editor startup. I did it in a UDeveloperSettings object so I could customize the binding, but you can probably figure out the right incantation to do it without such an object.

Sample:

#if WITH_EDITOR
void UMyDevSettingsObject::OnCommandsChanged(const FBindingContext& BindingContext)
{
	if (BindingContext.GetContextName().IsEqual("PlayWorld", ENameCase::IgnoreCase))
	{
		FPlayWorldCommands& Commands = (FPlayWorldCommands&)BindingContext;
		Commands.StopPlaySession->SetActiveChord(MyCustomOverrideBinding, EMultipleKeyBindingIndex::Primary);
	}
}
#endif

void UMyDevSettingsObject::PostInitProperties()
{
	Super::PostInitProperties();
#if WITH_EDITOR
	FBindingContext::CommandsChanged.AddUObject(this, &UMyDevSettingsObject::OnCommandsChanged);
#endif
}

Though the existing setting OP uses is probably best. :sweat_smile:
