SPE keyboard shortcuts

[Tim Grove]

Still enjoying using Stani's Python Editor!

I was editing a file when I accidentally stumbled across a keyboard 
shortcut which enlarged the fonts in the editor, CTRL-B. This "stumble" 
was actually quite useful as I can now read what I've been writing!!! 
Can someone tell me how to go the other way, and reduce the size of the 
font; preferably with another shortcut? Thanks.

Best regards,
