Tips for using IDEA.

You should consider to support Chinese UI.

You can reorder your class members with code folding: fold everything in the class and use cut & paste.
-- MikeAizatsky - 06 Jun 2002

You can use Introduce Variable (Ctrl-Alt-V) refactoring not only when refactoring code but also when typing it.
Type an expression and press Ctrl-Alt-V (no need to select anything!) to put it into a local variable.
-- ValentinKipiatkov - 04 Jul 2002

Example: 1+2| press [Ctrl-Alt-V]

If you have a local variable which is initialized in declaration, sometimes you later on want to initialize it in different ways based on some condition.
You can easily do it using "Surround with..." feature.

For example, if you have code: JCheckBox checkBox| = new JCheckBox("Click here"); panel.add(checkBox); press Ctrl-Alt-T, choose "if" or "if/else", and - voila: JCheckBox checkBox; if(~|) { checkBox = new JCheckBox("Click here"); } panel.add(checkBox);

I've compiled a Quick Reference Card for Idea.
In case you're interested, you can download it here.
Enjoy!

Idea (at least in version 3.0) doesn't provide a command to reformat java scriptlets in JSP pages, but if you cut the scriptlet contents and paste it in the same place, the paste will reformat according to your java indentation and line break rules.

If you have a class with lots of fields, and you want to extract those fields into a separate class -- first extract a super class using all those fields, then apply convert inheritance to delegation.

You can make log4j messages that appear in the system console have clickable links to the line that produced them. Use this pattern in your log4j.properties file
log4j.appender.stdout.layout.ConversionPattern=%d %5p - <%m> - at %c.%M(%F:%L)%n

If IntelliJ performance is sluggish for you, it may be because your on-the-fly virus checker is slowing it down by scanning each cache file when it is opened. I disabled my virus scanner for the Idea user directory, and it became significantly more responsive.

Want to navigate through all the errors of the proyect? Compile and use CONTROL+ALT+(UP/DOWN). This shortcut works although you are in the editor panel.
