Feature: combo to switch InputPlumber profiles

[LukeShortCloud]

A really handy feature would be to press a specific combination of buttons/keys to switch the profile. This would be most useful to switch from a controller mode to a mouse + keyboard mouse (and vice-versa).

For example:

• Hold LT1, LB1, RT1, and RB2 to switch from the default profile to mouse_keyboard_wasd profile
• Hold LT1, LB1, RT1, and RB2 again to switch from the mouse_keyboard_wasd profile back to the default profile

Perhaps it can be off by default to prevent accidental switching of profiles for users. I can imagine on SteamOS that it could be a support nightmare. This could also be temporary where a service restart would go back to the original settings.

I like the idea. There are a few technical challenges that might get in the way.

• Different devices have different "extra" buttons, so finding a universal solution using non-standard buttons will be a challenge.
• Using standard buttons has the caveat that when searching for combos we don't want to "bleed" the events unless we know the combo is not pressed. This means that using any of the buttons built in to all controllers will have the side effect of adding some delay to when the event is pressed or released.

I do want to rework how we detect macros to make it more flexible, i.e expect a second button press within X ms or send the keys as they are. Perhaps this is something we can tackle when we do that.

This would be neat to have for rounding out the Razer Tartarus Pro as it has a 'dedicated' profile button and LED matrix for this purpose already.
