Registering keystrokes for both OSX and VMware simultaneously?

Hello everyone,

I have Windows 7 installed as a virtual session within VMware Fusion 5.03.

I have a number of games which use their own internal voice communication protocols. For these, I have a keystroke assigned to enable push-to-talk functionality.

While this works without fail when VMware has the focus, the keystroke are not registered when using other applications in the host OS (snow leopard 10.6.8).

Is there any way to have the keystrokes registered in WMware Fusion from the guest OS?

For an example, I want to continue to use push-to-talk to communicate with my team mates for the game running in Windows 7 even though I'm working in say, Filemaker Pro in Snow Leopard.

Thanks.
