If you are experiencing issues with your wireless keyboard and mouse not working properly, perform the following steps to troubleshoot the wireless keyboard and mouse.
You may be wondering why your cursor keys along with your Home and End keys are not working properly. When you attempt to move your cursor from one cell to another using the cursor keys, the entire spreadsheet moves in that direction. Also the Home and End keys only take you to the far left or right of that row that is currently visible instead of taking you to the beginning or end of that row.
The simple solution might be that you accidently turned on your Scroll Lock. This is a special key that is seldom used today and exists near that upper right of the keyboard between two other keys rarely used, Print Screen/ System Request key and the Pause / Break key. Check your keyboard and see if the light for the Scroll Lock is on, if so that is likely the cause of your issue. Simply press the Scroll Lock key once to turn it off; you should notice the indicator light goes off as well.
