421075 - make Command-PageUp|PageDown switch between tabs

Status: NEW

(Firefox :: Keyboard Navigation, enhancement)

Description

Currently, the keyboard shortcuts for switching between tabs on Mac are Ctrl-PageUp|PageDown.  This makes the use case of closing selected tabs via the keyboard cumbersome, since you have to use Ctrl-based shortcuts to switch to each tab and then a Command-based shortcut (Command-W) to close them.

That use case would be much smoother if the keyboard shortcuts for switching between tabs on Mac were Command-based, and since the Command-based shortcuts aren't being used for anything else, using them doesn't displace any other functionality.

There would, of course, be a cost to no longer supporting the Ctrl-based shortcuts, although we wouldn't necessarily have to remove them to implement the new ones.  We could support both if we wanted to maintain backwards compatibility.
