Changing Font Size in RubyMine via the Keyboard

A co-worker asked if RubyMine has the ability to increase/decrease the font size (say if you were presenting on a projector). I didn’t know, but I researched it and here’s how you enable font size changes.

1. First open RubyMine.
2. Go to RubyMine -> Preferences.
3. Select Keymap from the list on the left
4. In the upper right search box, search for Font
5. You should see three options, namely Increase Font Size, Decrease Font Size and Reset Font Size
6. Double click on each of these options to add a Keyboard shortcut.
7. I added ⌘- (Cmnd-minus) for Decrease, ⇧⌘= (Cmnd-Shift-Plus/Equals) for Increase and ⌘0 for Reset
