Mr Poltroon

Wow, I advanced three text lines consecutively by executing an unintended, but dexterous, movement.

I picked up my keyboard, accidentally clicking 'enter', whilst moving my mouse, and I accidentally hit said mouse in the keyboard, clicking the left mouse button in the process, and by hitting the keyboard my finger slipped, scrolling down the mouse wheel as well.

Therefore, I clicked 'enter', 'left mouse button' and scrolled down in quick succession, advancing three lines.
You've got nothing on these skillz.
