I would like to request following features to improve the use of edge for pro users:
1. Shortcut support to expand the collapsed vertical tabs pane.
2.Once the tab pane is expanded, we should be able to use up and down arrow keys to move among the tabs instead of ctrl+tab. Also, the navigation using arrow tabs should be kind of circular list. From the last tab on down arrow we should be taken to first tab.
This will improve the accessibility when people have multiple tabs open during research over internet.
