novice question re "marked" and customkeys

[Peter Brigham MD]

"mark cards where..." is very fast and very flexible. Using a  
(possibly hidden) checkbox button should be quite feasible even with  
lots of cards. To "unbark all" you can loop through all the cards and  
set the hilite of the button to false -- be sure not to *go* to the  
cards, just loop through them by reference -- and that should be quite  
fast as well. (set the hilite of btn "barked" of marked card n to  
false) Or, 'mark cards where the hilite of btn "barked" = true' and  
then loop through the marked cards, set the hilite of btn "barked" to  
false, then unmark all cards. Cycling through the cards by reference  
is fast ('set the hilite of btn "barked" of marked card n to false')  
-- always, always, always avoid things like "go card n" within a loop,  
since that takes lots of time.
