Please read: To configure the shortcuts, open the addon page and click on the ⚙️ cogwheel button in the upper right corner, and then click Manage Extension Shortcuts. There are additional shortcuts as well. You can configure and use all of them at the same time. - There is a shortcut to open the new tab in a new window. - There is a shortcut to pop the current tab (or multiple highlighted tabs) out to a new window. - There is a shortcut to open a blank new tab to the immediate right of the current tab (i.e. instead of all the way to the right). Tip: Even without this extension, it is possible to middle click the refresh button to duplicate the current tab.
