When I attempt to select my push to talk button I am not able to set any non-modifying keys. Keys such as control, option, command, and shift can be set as PTT, including combinations. However I cannot combine these with normal keys such as letters or numbers. So if I tried to set my PTT to "Control+Shift+1" for example, Teamspeak would register it as "Control+Shift".

TS version: 3.0.16
OSX 10.10.3
My iMac is brand new so I can't imagine I changed any settings which would conflict with TS.
