how to modify keymap in ubuntu gnome?

You can do it with "xmodmap"...
But you will have to read a bit.

Perhaps try going up to the top taskbar and click on

System - Preferences - Keyboard

and/or

System - Preferences - Keyboard Shortcuts

Good luck and regards from

Also beside each shift key is a weird key that has some odd symbols on. The right-hand-shift key has / ? beside it and the left-hand-shift has \ | between it and the z key

link again and wonder if the difficulty is in reaching a command line? If so go up to the top taskbar and click on

Applications - Accessories - Terminal

Hopefully i'm not barking up the wrong tree again. Sorry about earlier

Again it looks like we haven't been able to help you fix this problem. Is it still a problem? Have you found a way to fix it from somewhere else? Please let us know how you fixed it, if you have also then marking this question solved would be great but if the problem still isn't fixed then maybe just re-post it again?

Apologies and regards from
Tom
