How do I force a key to enter just one character when being pressed?

Try this in the field script:

on keyDown var
    if the stillPressed of me = "true" then exit to top
    put var after me
    set the currentText of me to me
    set the stillPressed of me to "true"
end keyDown

on keyup
   set the stillPressed of me to "false"
end keyup
