I want to indicate which parameter is selected on the LCD by making a character blink. I know I can blink the cursor, but that doesn't really help me. Is it possible to make just one character blink?

alternate printing the character as the character you want, and then as a space character?

OK, I just made it work. Thanks for help. I ended up trying the following:

I printed the number.
Then, I used the setCursor command to move the cursor back to the same spot.
Then I used lcd.Blink(); to make it blink.
Then I had a delay(20);
Then I read the value of the POT position.
Then I looked to see if they pushed the button to confirm the selection.
Then I went back to the top if they had not confirmed the selection yet.

It works great!
