IntelliJ IDEA disable font increase/decrease on CMD+scroll
Settings | Editor | Enable Ctrl+MouseWheel changes font size
(On Mac it would be Preferences | Editor | General | Enable CMD+MouseWheel changes font size.)
IntelliJ IDEA 14.1
By default it is disabled and it can be found here:
File > Settings... > Editor > General > Change font size (Zoom) with Ctrl+Mouse Wheel
The option is still there in IntelliJ IDEA 15 EAP.
in Linux, before IDEA 11 i used Ctrl+ScrollWheel for change font size but now in IDEA 11 this feature has been removed
