Ctrl+Tab MRU

'Ctrl+Tab MRU' allows switching through tabs in the order they were visited before. By default this happens by pressing Ctrl+Y for going back in time and Ctrl+Shift+Y for the other way round. *** IMPORTANT TO KNOW *** Unfortunately Chrome doesn't drectly allow users to set Ctr+Tab as shortcut keys. So I suggest using the following trick to circumvent this: https://superuser.com/a/1326712. *** *** *** Tab switching also works on special pages (like chrome://), Chrome Web Store URLs, PDFs, XMLs or when the address bar is focused. In this case a temporary tab is opened to show the menu. To directly jump to a tab listed on the switcher menu, click on its title or icon. Drawbacks: - At the moment I don't have an idea how to avoid the temporary tab. It's required because I otherwise could not detect the release of the ctrl key (=end of the switching action) on special pages. - If you release the ctrl key too fast while the temporary tab is loaded I am unable to detect the key-up event, therefore the menu gets stuck. Please hit the ctrl key again to finish switching. - Recent tab order is not preserved when closing and restoring a window. Permissions: - 'Access your data on all websites': required to draw the tab list on top of the websites' content and to detect PDFs and XMLs. - 'Access your tabs and browsing activity': required to record tab order, open the temporary tab and to switch to the selected tab.
