Added convenience functionality where a user can automatically cut and ...

...copy a line simply by placing the cursor somewhere on the line itself before hitting the standard key combinations.

This is an extremely useful IDE feature in my opinion, especially for developers who prefer using the mouse as little as possible (it saves you at least 3 key strokes every single time you wish to copy or cut an entire line).

If we consider universal usability, then fewer keystrokes also mean greater ease of use for handicapped developers.
