Lyndel, you're my hero! :-)

Since I'm running Windows within VMware Fusion on my MacBook, it's a little more complicated in my case, though (and also, I'm using a trackpad instead of a mouse, so no wheel...).
On a Mac Control+<scrolling> magnifies the whole screen, which is an OS function, so it also works on the (full screen) VMware Fusion window and the shortcut is not passed through to the Windows OS running within.
However if I use Shift+Control+<scrolling> it's not intercepted by macOS and it works in Windows and PEP3 just as you described.
Now I can finally read what I type and don't have to debug stupid errors I made when mistyping ":" for ";" anymiore :-).

Thanks a lot!
