I have a Dell Inspiron 15 3537 laptop. As you know, we use 'alt+arrow key' to navigate forward or backward in a web browser, file explorer, etc. Now my left 'alt' key is working in this very manner. But my right 'alt' key would rotate my display when used with an arrow key. So I searched on the internet and disabled the 'hotkeys' from 'Graphics Options' under 'Intel HD Graphics Control Panel'.
Now all is fine other than that the right 'alt' key doesn't work. It won't even highlight the menu bar as the left key does. Nor would it navigate as mentioned above.
I can assure you that the right 'alt' key is working (as it does rotate the screen). Does anyone know how to make this right 'alt' key which has been rendered useless, work as normal?
Thanks!
