[WriteLog] Back to Entry Screen KB Shortcut?

[Eric Rosenberg W3DQ]

I'd like to set up a "Back to Entry Screen" KB shortcut, so I can bring 
the cursor back to the callsign entry field when the cursor is in 
another window.

This doesn't appear to be in the list of possible shortcuts.  Have I 
missed it?

Thanks,
