Use keys + mouse to scroll horizontally/ vertically

Press <Shift> + mouse scroll to scroll the sheet horizontally.
Press <Control> + mouse scroll to scroll sheet vertically.

IMHO, the default 'mouse scroll' should be vertical scroll and zoom should be activated by the <Control> key.
I would like to submit a patch for that too but is there anyone else in favor of such a change or should it stay like it is?
