It's possible to bind Escape in Controls (custom input bindings) and this immediately closes the Options menu

[hsandt]

In the Controls menu listening prompt:

If I press Escape, it will very quickly assign Escape key (if not conflicting) and go back to main menu. When I reopen Control settings I can check that it has been set indeed:

If Escape is already assigned in one of the customizable input actions and I try to set another one to escape, it will correctly notify me of conflict, but this will only appear for a very short time

Because it will still capture Escape input here too and not just close the warning popup but even go back to main menu, again.

I thought issue was with the key supposed to close menus, but I found there was no issue with gamepad button to go back (Xbox B), so it seems to be a issue with Escape only

Suggestions:
a. prevent assigning Escape key at all
b. support assigning Escape but capture the input and stops propagating it or ignore it manually with some flag so it does not also close the settings menu

There could be an option flag to decide which behavior to follow

Related issue (not opened yet): pressing gamepad L/R during "Listening to input" will immediately switch tab (doesn't happen with Page Up/Down, although you can still switch tab with Page Up/Down when seeing the conflict warning popup without having to close it first)

My workaround with local patch in my current project:

res://addons/maaacks_menus_template/base/nodes/menus/options_menu/input/key_assignment_window.gd

@tool
# LOCAL PATCH: added `class_name` to allow extending class instead of full copy just to override one method
class_name KeyAssignmentWindow
extends ConfirmationOverlaidWindow

res://menu/scripts/custom_pause_menu_controller.gd

# A customized version of addon key_assignment_window.gd
class_name CustomKeyAssignmentWindow
extends KeyAssignmentWindow


func _is_recordable_input(event : InputEvent) -> bool:
	if not super._is_recordable_input(event):
		return false

	var input_event_key := event as InputEventKey
	if input_event_key and input_event_key.keycode == KEY_ESCAPE:
		return false

	return true

and in res://menu/scenes/menus/options_menu/input/input_options_menu.tscn, overwrite the base script by attaching script above to KeyAssignmentWindow

However, this does not fix the issue of immediately closing Listening input popup and leaving Options menu altogether in just one press of Escape.

Thanks for reporting the issue, though I believe suggestion B is already implemented. Have you tried disabling the UI Cancel Closes option?
