Thank you.  Now it is fixed.

I don't know offhand, but I don't think that capability is in place.  I 
find holding down a key while panning to be a bit awkward, so I am also 
interested in alternatives.

Yes, matplotlib-users is the right place.  I assume you intended to 
"reply-to-all" on that last one, so intended it to go to the list. 
Apparently the settings on this list are unusual in that one must 
explicitly "reply-to-all"; it is not automatic that one's reply goes to 
the list.
