HI Carlos,

re:
> Is this possible in Options (zoom independent and together) and also a short-cut?

There is an option under Options > View > Rotate/Pan/Zoom options > "Link ortho views" which will keep the Top/Front/Right views to be all at the same zoom level. When that is enabled if you zoom in the Top view for example, the Front and Right views will also update.

Is that what you were asking about or is it something different?
