Is it possible rotate left/right when press a key via vizconnect?

It's seems like you defined invMat inside of a function, which called local variable, and not as global variable.
If you want to use invMat in your script you should use return invMat.
For example:

new_func(a,b):
c=a+b
return c

newVar=new_func(g,h)

If this problem is not as a result of what i described and is due to the vizconnect itself than i think you should explain what you try to use with: "I tried to use the keyboard keys like up for up, down for down ect and i tried to use the mouse for orientation".
Make sure you connect the transport to input device or tracker in order to use it.
