Get Mouse Position

Hi everyone, 

I am clicking on a found object on the screen, then i need to move mouse and click, e.g. 20 pixels down from current click position.

Mouse - Move Action will ask me current position.

I am having trouble finding a way to:

1. Either get current mouse to be able to use as input for the Mouse - Move action.
2. Or a way to move mouse e.g. 20 pixels on Y from current position after an object found click.

If you have any questions please let me know. Thanks.
