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.
