Teclas de acceso rápido en Eclipse/Eclipse shortcut-keys

CTRL + D
Delete row. Try it! You no more need to grab the mouse and select the line, no more Home, Shift + End, Delete. Quick and clean.

ALT + Up/Down Arrow
Move the row (or the entire selection) up or down. Very useful when rearranging code. You can even select more rows and move them all. Notice, that it will be always correctly indented.

ALT + Left/Right Arrow
Move to the last location you edited. Imagine you just created a class Foo, and now you are working on a class Boo. Now, if you need to look at the Foo class, just press Alt+Left Arrow. Alt+Right Arrow brings you back to Boo.

CTRL+SHIFT+O
Organize imports. What happens when you first use a class you have not yet imported? You will see an error. But when you press this magical combination, all your missing classes will be imported, and the unused imports will vanish.

CTRL+1
Probably the most useful one. It activates the quick fix. Imagine you create a class, which implements some interface. You will get an error, because the inherited methods are not yet implemented. While you are on line where the error occurs, press this combination to activate the quick fix. Now, select the "Add unimplemented methods" option. You can use the quick fix at every error you ever receive.
Quick fix comes handy in other situations too. My favorite is the "Split variable declaration". Sometimes I need to broaden the scope of a variable. I activate the quick fix, split declaration, and use alt + arrow to put it where it belongs. You can find even more usages: Convert local variable to field, rename in file, Inline local variable..
You could use the "Split variable declaration" on the bar variable, and then move it with Alt+Arrows above the try block..
Or you could use the "Add unimplemented methods" fix here.
The best thing you can do if you see an error is to use the quick fix.

CTRL+SHIFT+T
Open Type. Imagine, that you need to have a look at the Foo class. But, where is the Foo class? Is it in the Boo project and in the foo.bar package? Or somewhere else? With this shortcut, you don't need to know. Just press it, type Foo and you are in.

CTRL+E
Shows you a list of all open editors.

CTRL+F6
Use to move between open editors. This is an slower alternative to Ctrl + E. Comes handy in a situation when you want to periodically switch between two editors, something, what is nearly impossible with Ctrl+E as it sorts entries quite randomly. Or you might just use Alt+Arrows..

CTRL+F7
Move between views. When in editor, press Ctrl+F7 to switch to the Package Explorer, or hold Ctrl and press F7 multiple times to switch to other views.

CTRL+F8
Move between perspectives. The same as previous.

CTRL + F11
Runs the application. What gets launched depends on your settings. It will either launch the last launched class (my preffered way) or it will launch currently selected resource (the default way). If you want to change its behavior read the previous post.

CTL + N
Open new type wizard. This is not very quick because you have to select the wizard type (weather you want to create new class, jsp, xml or something else) in the next step. Much faster way would be if you could just hit the shortcut and invoke the particular wizard. It is possible, just keep reading..

CTRL + M
Maximize or umaximize current tab.

CTRL + I
Corrects indentation.

CTRL + SHIFT + F
Formats code. You can make a beautiful looking code out of a mess with this. It requires a bit of setup, but it is well worth it. You can find its settings under Window->Preferences->Java->Code style->Formatter

CTRL + J
Incremental search. Similar to the search in firefox. It shows you results as you type. Don't be surprised, if you hit this combination, nothing happens - at the first glance. Just start typing and eclipse will move your cursor to the first ocurence.

CTRL + SHIFT + L
Shows you a list of your currently defined shortcut keys.
I don't like your shortcuts
Such is life nowadays. Remember, you can always change those bindings to match your preferences. Open Windows->Preferences->General->Keys. Now you can use the filter to find your shortcut and change its binding.Effective Eclipse: Shortcut keys
You should try to keep your hands on keyboard. The less you touch the mouse, the more code you can write. I am trying to keep the mouse laying still and control the IDE completely using keyboard. What do you think is faster: pressing ALT + C or right clicking the project, selecting Team -> Commit?
