My left and up arrow keys don't work

1. • 1 Open and power on the laptop.
     
   • 2 Wait for the laptop to fully boot.
     
   • 3 Locate the "Scroll" button at the top-left of the keyboard. It is under the volume panel and between the "F12" and "Pause" keys.
     
   • 4 Press the "Scroll" button.
     
   • 5 Test it by opening a spreadsheet and using the arrow keys to move around on it. You can open your Microsoft Excel program or create a spreadsheet online by using Google Docs (free online productivity software). The "Scroll Lock" function will keep the current cell selected while the screen moves.
     
   • 6 Press "Scroll Lock" again to turn it off.
     

Press the "Menu" button on the remote control and use the arrow buttons to scroll down to the "Parental Guide" option, then press the "Enter" button.
Type in the default parental code "6688" if you have not set your own code. If you have set your own code, type it in. If you set your own code and forgot it, override it by using "6688."
Use the arrow keys to switch the parental lock to "OFF." This allows all programs to be viewed no matter the rating. Press the "Exit" button on the remote and start watching all your channels

This is either the Num Lock or the Scroll Lock. To turn off the Num Lock, look at the top left of your number pad on the right side of the keyboard, and press the Num Lock key. To turn off the Scroll Lock, press that key in the middle of the top row of 3 keys above your arrow keys.

Short answer:
There are two ways to switch from one machine to the other with the keyboard
1. Press Scroll Lock key twice, then the Up or Down arrow key.
2. Press Scroll Lock key twice, then enter 01 or 02.

Long answer (from the manual posted at www.belkin.com):
You can select which computer to operate by either the front-panel push button
located on the top of the Switch or through hot key commands. Note that it will
take 1-2 seconds for the video to display after switching. This is due to the
refresh of the video signal. A re-synchronization of the mouse and keyboard
signal also takes place. This is normal operation and ensures that proper
synchronization is established.
You can conveniently change ports on the Switch through a keyboard command
sequence using the "SCROLL LOCK" key and up and down arrow keys. To send
commands to the Switch, press the "SCROLL LOCK" key twice within two seconds.
You will hear a beep for confirmation. Then you can press the up or down arrow
keys to switch between ports.

You can switch directly to any port by entering the Switch port number you wish
to use. For example, if you press "SCROLL LOCK", "SCROLL LOCK", "2", the
computer on port 2 will be selected.
AutoScan Mode
In AutoScan mode, the Switch remains on one port for eight seconds before
switching to the next. This time interval cannot be changed.
To enable AutoScan mode, press "SCROLL LOCK", "SCROLL LOCK", "S".
Note: There is no mouse or keyboard control in this mode by design, in order to
prevent errors. If it were enabled, the user could move the mouse or use the
keyboard while the KVM Switch is switching to the next port. This could interrupt
communication between the computer and Switch that might cause erratic mouse
movement, or result in errant display of characters when using the keyboard.
To disable AutoScan mode, press the space bar.

Hit your left Ctrl key twice

That would be the Scroll Lock. Do you have a Scroll Lock key? Press it.

Thanks for using Fixya.

NumLock is on. Look for the Fn key in the lower left corner, and lookint in the top right, the NumLock key.

The key that activates thenumeric pad arrow keys it is called "num lock", and it is located on top of the numeric keypad.

Laptops may have additional function buttons to activate the arrow keys.

Found this little bomb shell after about 30mins of looking for an answer.
