it's easy

Learned it's pretty easy to assign a keyboard shortcut to a script on Stellarium. Told Chris.

This pertains to his query about zoom to a 30 degree field. It can be done with the script console with a direct command but it's clunky and not practically in a presentation with humans watching. But if one makes a script, it is easy to invoke it.

Now, some weirdness ensued. The Ctrl + number or Alt + number keyboard shortcuts were not tolerated. Why?! Stupid that it is not explained...

I used, in the end, simply 3.
