Good guess, but my GPU is AMD. Edit: Just tested, AMD uses the same key combination for opening the Radeon app. That explains it.

Thanks m8.

Alt+R is a default hotkey for a performance overlay in Nvidia GeForce. Could be that, or something similar. It's unlikely to be the game itself.

I've tried to use Alt+E as "eject" hotkeys for my TC and and towers. Of course, sometimes I miss it, and tap Alt+R instead, and when I do so the game pseudo-alt-tabs out or changes window focus out of the game. In the meantime nothing in the game is clickable.

This happens in the main menus as well as in game, and *only* with Alt+R, not Alt+V, Alt+H, Alt+T, or any other letter keys.

Basically, Alt+R specifically is unusable as a hotkey in the game. I guess my question is: What the fuck, why? Can't just be me.

Alt+R hotkey, what's up with it
