Looking for a solution to my Samsung lap top

Solution
I had an issue with my toshiba laptop at one point where some keys were not working correctly, it turned out that the cntrl key was stuck. You may have a similar issue where a key is stuck, it may not be physical more like the system didn't register that it was released. Try clicking all your keys several times in succession and see if that helps, if not restart and if it still persist it's possible the keyboard is damaged.

In most laptops the keyboard is fairly easy and inexpensive to replace yourself.
