Starting at the last location.

[acosmicjoke]

I'd like to start keynav at the location where the last one ended. I tried to do this by adding this line to the config file:
alt+semicolon start, history-back
However, what this actually does is start keynav and goes back in history twice. I'm not sure if this is a bug or I'm just missing something. When start keynav normally, than press the history-back hotkey everything works as expected and the keynav pointer-thing returns to the location the last one ended.
