Eclipse Hotkeys and Shortcuts
Many programmers using Eclipse are having a hard time editing simply because they are yet to use the IDE more efficiently. Here are most of the hotkeys and shortcuts I use and I would like to share these with you. I currently use Eclipse Ganymede, but I have been using these hotkeys since Eclipse 3.1. The hotkeys I use very commonly are the following:
| Ctrl+Shift+O | Organze imports. This saves you from people telling you to remove unnecessary imports and also obtains the import classes that you forgot to import. Import import import. |
| Ctrl+Q | Go to last edited change. This is useful when you are browsing too much code in other files then forget what file you were currently working on and most importantly, what exact line and column you were. |
| Alt+Up or Alt+Down | Move line up or down. Very useful when moving blocks of code around like putting it inside a loop or rearranging the program logic. Simply select the lines you want to move then use the hotkey. |
| Ctrl+Shift+T or Ctrl+Shift+R | Open Type or Open Resource. Know the class name or the properties file name but forgot which project or package it resides in? Use this hotkey. |
| Alt+Shift+W, P | Have 100+ classes in your project, and dont have time to memorize all names? Use this hotkey to show the the file you are currently working on in the Package Explorer. |
| Ctrl+D | Erase current line. Pressing Home, another Home(to get the indentation spaces), Shift+End, Backspace is replaced by a hotkey. |
