Keyboard toggle of technique doesn't work, but..

I'm seeing a problem where setting a technique toggleable like this doesn't work (pressing the key doesn't do anything):

However, a uniform like this will properly update:

I'm trying to detect the very same keycode within the same app, but one method works and the other doesn't.
The app runs on DirectX 10.

The first method gets ignored by ReShade since a recent update. I assume thats intended since it's in conflict with hotkeys assigned for techniques within the gui (or .ini respectively).

Hmm I can't find a way to toggle individual techniques from the GUI side.

1. Right click the tequnique.
2. Set the toggle key.
3. Press key to toggle techniques.
