Anyone ever seen a 'move to breakeven' script?

Has anyone seen a script around where I can assign a hotkey such as Ctrl + E where it automatically moves my SL to breakeven? That would be very useful for me.

If not, anyone want to try their hand at coding one?

thanks to Zen Leow

with the other script you can set a hotkey for cosing any position size you want, to lock in profits...

What does that mean, "lock in profits?"

BTW, thanks for the script. It's exactly what I wanted and needed.
