PTT key combinations possible?

[splash99]

On the Windows version of Vent it's possible to use multiple key combinations as a PTT button. On the Mac version it will accept only one key (there's no equivalent of "Use Direct Input to detect Hotkey" checkbox). Is there a way to be able to set a key combination in the Mac Client?

(NB: It's not that I want to complicate things with multiple key combos, just that my wife has a new gaming keyboard with macro keys and wants to use a conveniently positioned macro key as her PTT button and the only way to get Vent to recognise it as a PTT button is to map a macro to a standard key on the Qwerty panel).

Any ideas much appreciated.
