Calculator Dialog Keyboard Entry?

Hello,
Is there an easy way to get the calculator dialog to accept direct keyboard entry in addition to clicks/touchscreen events? I ended up disabling the dialog from the ui file but I sort of like it but I don't want to keep using the mouse.
 

find the calculator.py file (linuxcnc/lib/python/qtvcp/widgets/)

change line from true to false:
self.display.setReadOnly(False)

I don't see a problem leaving it like that. Please confirm and I'l make it permanent.

Thanks Chris! confirmed, it works perfectly.
