In a Visual Studio, you would use Ctrl+L, whereas in Eclipse I am forced to select a line or, if it is empty, go the beginning of the line before clicking
To quickly find shortcuts, hit Ctrl + L, Ctrl + L (Ctrl+L twice), then type something approximating what your command does in the filter text for the key assignments. This works pretty well for most shortcuts, although it can be a bit tricky for some where the name of their menu assignment bears no relation to that of their command in this list (for instance, Team->Revert to base appears in the keys list as 'Replace with latest from repository'), so sometimes a little lateral thought is required :-) If no shortcut exists, it's easy to add one in the keys dialog.
