Keyboard problem solved

So, the answer to my March 19 post is, "Yes, I screwed up something with my keyboard when installing Ubuntu!" Luckily, the problem was easily remedied. I had accidentally selected the "English International" keyboard layout. I found this out when I went to the system menu, selected "preferences" and then "keyboard" and then "layouts." You can add or remove layouts, so I added the U.S. English layout and removed the international one. Easy enough.
