Anahnerbe wide screen tdc question

[bstanko6]

I was being adventurous and trid the widescreen Aneherber I'm not sure how that is spelled.

Anyway, I play 100% realism and do my own plotting all of the time.

I like this GUI but it seems that I cannot lock/unlock the tdc from the attack periscope. Is there a way to do this without going back and forth to the tdc screen?

Any help would be appreciated.

P.S. I understand that the notepad is active and I can use that, but I don't use it. I prefer to get range manually and manually input all data in the tdc, which is why I ask if there is a way to lock/unlock the tdc.
