It depends,
if it is a laptop it might be the function type key and the left or right arrows.

When I type a letter it sticks and keep typing the same letter.

Keyboards sit out exposed to all kinds of debris. Dust, ashes and so on can settle into the area around the keys and cause problems. Turning the keyboard upside down and patting it on the backside might help. You'll be amazed at what comes out. A can of compressed air might also do the trick but again, upside down.
Keyboards are cheap and they really aren't worth fixing. But if it becomes too frustrating, and it's not a wireless keyboard, you might try putting it in the dishwasher upside down. This is a last resort when you've given up and are ready to buy a new keyboard. And I'd only do this if someone spilled something on it.
If it doesn't work now, this won't make it work any less. Well, actually, it could. LOL
Good luck.

I touched a button on the keyboard that turned the page sideways.. it turned it to the left. how do I turn the page right side up?

Actually you hit a combination of keys. Most likely you hit Ctrl+Alt and an arrow key. Try Ctrl+Alt+the up arrow. If that rotates the screen to upside down, repeat the combination twice more (or use Ctrl+Alt+the down arrow twice).

If that doesn't work, if you have a Windows OS, try the Screen Resolution or Graphics Display settings. Right click on the desktop anyplace with no running programs or icons, select Screen Resolution and then change the drop down for Orientation. This works on my desktops. For my laptop, it's the Graphic Display and then a similar orientation label.

I hope this helps.

Used ctl,alt,page up to reverse screen....cant get it back!

Using keys on the lower right of the keyboard, reverse the process. For instance, if you accidentally pressed CTRL + ALT + HOME to turn orientation upside down, press CTRL + ALT + END to turn it right-side up. Likewise, if you pressed CTRL + ALT + PG UP, press its opposite, CTRL + ALT + PG DN.

Ways to take care of yaour keyboard

Things You'll Need
  • Computer Keyboard
  • Cotton Swab
  • Isopropyl alcohol
    • Before doing any type of cleaning make sure to turn off your computer and disconnect the computer keyboard from it.

    • Once the keyboard is unhooked, turn it upside down and grab the can of compressed air. With the keyboard still upside down, tap it and watch all of the dust and grime fall out. Repeat this step 1 or 2 more times until nothing falls from the keyboard when you turn it upside down.

    • Take the cotton swab and dip it into the alcohol before cleaning the sides of the keyboard

  • If you want a more thorough cleaning, remove all of the keys from the keyboard and take a moist cloth and wipe away the dust. Also use the can of compressed air to vanish away grime particles.

  • Never use a wet towel on your computer keyboard

  • Turn off your computer and then unplug and reseat your keyboard. Occasionally computers will experience glitches that prevent drivers and software from loading correctly. Restarting your computer and plugging your keyboard back in will often solve the problem. If not, View your keyboard's status in the Device Manager. To access the Device Manager, open the Windows Control Panel and click on "System and Maintenance." Scroll down to the third section from the bottom and click on "Device Manager." In the menu bar at the top of the Device Manager window, press the button called "Scan for hardware changes." Windows will now scan your computer for any new or malfunctioning hardware. Once the page refreshes, go down the list of devices and click on "Keyboards." Right-click on your keyboard and select "Properties." A new screen will then pop up to tell you whether Windows thinks the device is working properly. If the system indicates the keyboard is not working properly but doesn't give you instructions on how to fix the problem, .

  • Visit your keyboard manufacturer's website and view the support or troubleshooting sections. Find the "Search Help" (or similarly named) box and enter your keyboard model number (this can be found on the bottom of your keyboard on a sticker or engraved in the plastic).

    Screen has rotated. What keys do I use to fix this?

    This is a tricky problem, If you are saying your monitor screen is upside down. Using your mouse right click any where on the desktop and chose properties, on the properties window chose settings and look on this tab (now every video card is a bit different) But look for an orientation tab and click the button for normal or rotate 180 degs. Due to it being upside down the mouse will work backwards up is down sort of thing it may take a try or two, or turn your monitor so you can see the words.

    dirt between the buttons can be one reason, another is wear between the contacts, keyboard is easy cleaned, just put it upside down and use stiff brush to clean between the buttons.

    if contacts are dirty, usually caused by spill (my son spill coffe at least twice a year on keyboard during last 10 years of his programming...). easy way is to if use corded keyboard (if wireless start from step3)
    1. switch off the computer
    2. remove keyboard cable from socket
    3. remove batteries if installed
    4. turn keyboard upside down
    5. remove all screws
    6. turn back to correct position
    7. remove top frame (with keys)
    8. check for any physical debris and remove if any
    9. lift rubberised pad and whipe bottom of it with methylated spirit, allow to dry
    10. check if plastic film can be separated, if so, whipe each layer with methylated spirit, do not under any circumstances break any of printed conduit lines.
    11. when all is dry, put all back together in reverse order. watch for little springs present in some models.
    12. go to shop and buy new keyboard... they are about $5.00 to $250.00 in that broad range you can find something suitable and affordable...

    this is general description of the keyboard "gizzards", they vary slightly between the brands but principle is this same. if you have keyboard made before 1994, it will be electro-mechanical switches and that will cause more trouble...

    WHile cleaning my legitech keyboard, I made the desktop appear upside down on the screen. How do I invert?

    The keystroke combination to flip the image upside down isCTRL-ALT-downarrow key... to flip the image rightsideup again, pressCTRL-ALT-up arrow

    If this does resolve the upside down image.
    Check your video card graphics settings. Nvidia has something called NVrotate:
    Right click your desktop, select properties. Go the settings tab.Click advanced. There do you have a tab for your graphics card? If you do, After selecting the tab it displays options. NVrotate. That rotates the screen.

    Good luck and hope this helps!

    Keys not working!!!

    got something stuck under the keyboard keys? Turn the keyboard upside down and give it a good shake.

    Check the connection in the back of your PC - make sure none of the pins are bent if it isn't USB.
