All my settings were correct and no other software running in the background
that would alter the keystrokes or remap my keyboard. I finally tried a
different keyboard and the Ctrl Home and Ctrl End functions now work. Oddly,
these were the only two functions that didn't work on the old keyboard, so I
had eliminated the keyboard as being the culprit.
Thank you both for your help and advice. It is comforting to know that
experts like you are readily available and take the time to respond to
questiions such as this. You are greatly appreciated!
