Microsoft has recently introduced vertical tabs to Edge, allowing users to regain vertical screen space, which may be used for content instead of chrome.
However, most folks are still won’t too horizontal tabs, and acknowledging this, Microsoft has added a keyboard shortcut within the latest Edge Canary to modify quickly and simply between vertical and horizontal tabs.
Now, simply pressing Control+Shift+Comma will allow you to easily switch between the modes.
Pressing the key combo results in the subsequent transformation.
The improvement is now available in Edge Canary Build 93.0.925.0.
