This is the coolest function from TextPad and lets you place unlimited line markers in your code. Then by pressing F2 you can jump instantly between each marker.
So if I was working on a big file and there were 3 function in particular I needed to switch between I'd put a marker in all 3 of them (Ctrl+F2) and then press F2 to jump around.
Currently Sublime only supports 1 marker which is a pitty.
