Markers to jump instantly between lines of code or functions

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.
