Right now I am using the Darcula theme. I want to change the default font to something else. I go into Editor > Colors & Fonts > Font but all the op
We can change the font size according to CTRL + mouse wheel which is really easy to use it !!! To use this feature select File -> Settings -> Editor -> General -> select the checkbox of Change the font size (Zoom) with Ctrl + Mouse Wheel
I hope it's helpful.
