I'm running Blender 2.77 on a MacBook Air with OSX 10.11.6 with just the built-in keyboard and trackpad (I mostly script stuff). When I type Ctrl++ it doesn't make the font in the Python console larger, it just shows a string of "===". I've tried all kinds of other two and three-key combinations, but the font never gets bigger.
I'll give a talk introducing Blender scripting to some Python programmers, and I'd really like them to see what's going on there. I'll take any kind of work-around that makes the text bigger without chaning the Python console window size edit: or changing the font size in all the windows at the same time.
I looked around in preferences and couldn't find an explicit font size for the Python console, but there may be some keyboard mapping I can do?
I bought the computer in the far east and it types in Traditional Chinese as well - I don't know if that influences the settings. Another person with same situation here (MacBook Air, OSX, Chinese Keyboard, Blender) had no problem with it.
above: Ctrl++ just gives equal signs
above: couldn't find anything helpful here
