Hi MPSchmied, you can set up a keyboard shortcut for Zoom Area by using this for the command part of the shortcut key:

script: var v = moi.ui.getActiveViewport(); if ( v ) v.interactiveViewChange('zoomarea');

That will trigger the area zoom on the viewport that the mouse is over.

But you can't set a shortcut just for ctrl+shift on their own, those are meant to be used as modifier keys that can be used in addition to another key.
