. A choice may be selected using the choice number.             <number><CR>

. An abbreviated name may be typed for the menu choice.         <name><CR>
  This will be used to match the text for the menu prompt
  as displayed on a screen. NOTE that the menu will select
  the FIRST matching choice in the case of multiple matches.

. The <UP-ARROW> and <DOWN-ARROW> keys may be used to select a choice. 
  When either of these keys is pressed the menu program will highlight
  either the last or first choices as appropriate.  Successive arrows
  will move the highlighted choice up or down one.  If <CR> or <SELECT>
  is pressed when in this mode then the highlighted choice will be
  selected.  If <HELP> is pressed then choice specific help may be given.

. The selection may be made as n m ... p.  That is: the choice
  numbers required (as if typed individually) typed as numbers,
  separated by spaces.
