Can you add zoom in/out & rotate keyboard shortcuts for iPad?

Hi,

I would like to request that you add keyboard shortcuts for zoom in/out and rotate left/right. It would also be great if you can have the default be some percentage, ie: 10% each button click, and maybe with a modifier key it would be finer grain control, ie: 2-5%. 

I like using a macropad to speed up my workflow and would like to program my pad to do this.

thanks
