You can use 'Command' + L to find line number in eclipse.

You can use Ctrl + L to jump to specific line number

You can find a large list of eclipse shortcuts here: http://javatutorial.net/eclipse-shortcuts

As you are aware CTRL+L goes to a particular Line, there is also CTRL+Q to go to the last edit location. The is no key combination in Eclipse to go to a particular Line and Column.

You can use a Keyboard Macro (available as hardware in some keyboards and included as software with some other keyboards). An explanation for Microsoft is here: http://support.microsoft.com/kb/237179 .

A Program like Autohotkey http://www.autohotkey.com/ can also be used.

Ctrl+L Jump to Line Number. To hide/show line numbers, press ctrl+F10 and select 'Show Line Numbers' There is no way to go to a particular column according to my knowledge.

On OSX, the shortcut is ⌘ + L
