Recently, I started to work with IntelliJ. But, honestly, after several years with Eclipse, it's hard to be effective because of key shortcuts which are different between the two IDEs. A little request on Google and I found this (great!) :
| Description | Eclipse shortcut | IntelliJ Shortcut |
| Navigate a Java Type | CTRL + ALT + T | CTRL + N |
| Navigate a Resource | CTRL + ALT + R | CTRL + SHIFT +N |
| Last Modified Source | ALT + Left arrow | CTRL + ALT + left arrow |
| Debug | F11 | Shift + F9 |
| Open Declaration | F3 | CTRL + SHIFT + B |
| Open Hierarchy | F4 | CTRL + H |
| Organize Imports | CRTL + SHIFT + O | CTRL + ALT + O |
| Find | CTRL + F | CTRL + F |
| Find Again/ previous | F3 / SHIFT + F3 | F3 / SHIFT + F3 |
| Step Into | F5 | F7 |
| Step Over | F6 | F8 |
| Step Out | F7 | Shift + F8 |
| Resume | F8 | F9 |
| To find impl of an abstract Method | ? | Ctrl + Alt + B |
| To find usage | CTRL + SHIFT + G | Alt + F7 |
