Essential Shortcuts in Eclipse, Netbeans and IntelliJ IDEA

Make your life easier with these practical shortcuts in Eclipse, Netbeans and IntelliJ IDEA. The cheat sheet is divided in three sections, based on the usage:

• File navigation / working with files
• Search in the project / files
• Code assistance, code completion or parameter info

The shortcuts are for OS X, but in the most cases, the ⌘ key corresponds with Ctrl and ⌥ with the Alt key on Linux or Windows.
