Wait for specific cedrus key

[VizMars]

My cedrus handler triggers an event viz.sendEvent(CEDRUS_BUTTON_DOWN, response['key']) every time a cedrus button is pressed.

How can I pause my Experiment until a specific cedrus key is pressed (e.g. button 6 is down)?

You can use viztask and the waitEvent (http://docs.worldviz.com/vizard/#commands/viztask/waitEvent.htm) command to wait for the cedrus button event.

But in this case every cedrus button resumes my experiment.

Are you using the vizxid module to get the Cedrus data, like the example posted here (http://forum.worldviz.com/showpost.php?p=17934&postcount=4)? If so, you can wait for a specific button press:

#Wait for button 3 on XID to be pressed
yield vizxid.waitButtonDown(3,d)

I'm using pyxid. But I'll have a closer look at the implementation of waitButtonDown.
