WCT-Version: 1.12.2-3.11.87
I am using "F6" & "F7", my open terminal hotkey is "R".
No other hotkeys are interfering.
In the "normal" Terminal it works just fine.

I recommend updating WCT, though, that won't solve this issue..just a suggestion. I'll look into how AE2 is doing this (if they're even doing anything at all) and see what I can do. This is more of a feature request than a bug since it's purely a mod interaction issue. Thanks for reporting :)

so after testing..this actually works fine..you just need to hold Ctrl while pressing R/U..this is the way AE2 functions as well
