From the past few days, a strange problem has occurred in my laptop's keyboard.
The right shift key works with all arrow keys except the left arrow key and the left ctrl button does not work with left and right arrow key.
Now, this makes it strange as only two combinations in ctrl and one combination in shift key is not working and rest are working fine.

Well if anything got on/in the keyboard that could cause this. Or if the keys (or the keyboard) is damaged as well can cause it.

But before going that route first I would try this.

1. Uninstall the keyboard driver(s).
2. Reboot the computer (yes without installing the driver(s).)
3. When the system restarts it should install the drivers.

If this doesn't resolve the problem, try turning off the laptop and connect an external keyboard. Turn it back on and see if that one works completely fine. If yes, then it is the attached keyboard that is the problem. So, again, I would be checking for damaged keys, something in the keyboard (food, dust, liquid, etc.,) and also check the connections to make sure nothing is loose.

NOTE: If this laptop is still under warranty you should not do any physical work on it yourself, or you would void the warranty. Should that be what is needing fixing (hardware) or another issue you can't fix on your own, then I would contact the manufacturer about it.
