Shift 8ik, keys not working

[surprisesbrian]

i'm a newbie here and hope this is the right forum. it doesn't seem to be a hardware problem.

in lower case, or without the shift key, all my keys work normally. However, when i try type 'Shift-i" nothing happens. When i type "caps-lock-i", i get "I".

The same is true for: 8, i, k and ",". Also, my cursor isn't jumping to the last position in the line when i use [right side]Command-rightarrow. it does when i use [left side] command-right arrow.

My six-year-old son plays a few games on the computer and may have changed some settings by accident. i cannot find whatever settings he may have changed.

Please help, even if your help is telling me where i should post this request.

I have typed out my keyboard keys so you can see which ones aren't working and under what circumstances:
Have a look as i type the keys in order:

Capslock

1234567890

QWERTYUIOP

ASDFGHJKL;

ZXCVBNM<> All okay!

Holding the left-side shift key

!@#$%^&*()

QWERTYUOP

ASDFGHJKL:

ZXCVBNM<> No “I”

Holding the right-side shift key

!@#$%^&()

QWERTYUOP

ASDFGHJL:

ZXCVBNM> No “*”, “I”, “K”, “<”

Free (No shift or capslock)

1234567890

qwertyuiop

asdfghjkl;

zxcvbnm,. All okay!

The problem fixed itself or anyway has gone away.
