IDE displays unreadable!

My cat walked over the keyboard and now my interface font has shrinked to the point that nothing can be seen! (see screenshot)
Can someone tells me what happened and how to revert it to normal?

Haha, best bug ever :rofl:

I guess your cat somehow activated the Chrome zoom. To undo, try this: Windows and Linux: Press Ctrl and + . Mac: Press ⌘ and +.
