NetBeans IDE lets you quickly and easily develop Java desktop, mobile, and web applications, while also providing great tools for PHP and C/C++ developers. It is free and open source and has a large community of users and developers around the world.
Quite by accident (and a little annoyingly), I discovered that there is a nifty little “shortcut” to increase or decrease the text size in the Java-powered NetBeans IDE, basically the ability to zoom in and zoom out on your code.
To do this, simply hold down the Ctrl button and scroll with the mouse wheel – essentially the same trick you would use to zoom in or zoom out of a web page using any modern browser.
Useful in a way I guess.
[UPDATE] NetBeans 7.2 changes the behaviour slightly – now you need to initiate a press down click on the scroll wheel whilst scrolling to increase/decrease the font size. No keyboard assistance required!]
Anyway, if you want to make more permanent changes to your default font, font size and color scheme, you could always just open up the Tools -> Options -> Fonts & Colors menu…
(Also, if you want to disable this functionality in the IDE, simply go to Tools -> Options -> Keymap and change the entries under Zoom Text In and Zoom Text Out actions.)
