Cannot use mouse move or display numbers or displa

Hopefully, I can attach the two screenshots involved. I am using a program called Timeslips. The first attached screenshot allows me to use super numbers quite effectively. However, if I have to change the date, super numbers allows me to open up the second attachment. However, nothing allows me to avoid physically using the mouse to change dates.

Any ideas?

If I cannot attach the screenshots I will email them.

Thanks so much,
