Investigate option to either disable, or reassign ctrl + mousewheel combination to navigate between tabs

[rotemdan]

The default behavior of this combination is to zoom the current page in or out. However that doesn't seem to work well with using ctrl as a "tab scope" mode modifier. Investigate if it is possible to disable the zooming behavior or allow it to be used to navigate between tabs instead.

(However a disadvantage of this is that pages not covered by the content script would fall back to the default zooming behavior, creating an unwanted effect).
