I would like to allow ‘^’ to be an input for the keyboard. This is because the fmri scanner will generate this when it begins. For some reason, it does not seem that ‘^’ is recognized. I am able to run my program with other inputs, e.g. ‘space’, but ‘^’ is ignored. I am running this in builder, but this is the code that is generated.

if key\_trigger.status == STARTED:  
theseKeys = key\_trigger.getKeys(keyList=[’^’], waitRelease=False)  
if len(theseKeys):  
theseKeys = theseKeys[0] # at least one key was pressed

Go to the Coder view and select a demo called something like `what_key.py` from the Demos menu. This gives the actual code for a given key, which doesn’t necessarily match the apparent symbol in all cases.
