I recently purchased the seenda slim universal bluetooth keyboard from amazon and saw there was an equals sign on the enter key in the numpad area. The thing is I can't figure out how to use it. I tried pressing "shift" + "numpad enter key" and "fn"+ "numpad enter key" and then all three and no luck.
How to Fix the Enter Key Not Working on Windows 10?
Restarting Your Computer.
Reinstalling Your Keyboard Driver.
Updating Your Keyboard Driver.
Adjusting Your Keyboard Settings.
Configuring Your Wireless Keyboard.
To create an equal sign using a U.S. keyboard press the equals key (same key as the plus ( + )), which is left of the backspace or delete key.
