Ctrl + D
Deletes the current line. By far my most frequently used shortcut in Eclipse.
Ctrl + Up Arrow, Ctrl + Down Arrow
Moves the current line up or down. Also very frequently used.
Ctrl + /
Sets the current line to be a comment. This works as a toggle: if the current line is already commented, this shortcut un-comments it making it active code.
If you type all the upper-case letters in the name of a class, then press Ctrl + space, Eclipse will replace it with the name of the class. If you type only some of the upper case letters, such that more than one class can match, Eclipse will open a list and allow you to select the class you need.
