Bonjour Yves,

put this in the card-script:

## fld 1 is the list-field.

on keyUp lekey
   if lekey is "a" then
  ## or whatever is your first letter
     set the scroll of fld 1 to 0
     exit keyup
     ## will scroll to top
   end if
   put lineOffset(CR & lekey, field 1) into lo
   set the scroll of field 1 to lo * the effective textHeight of field 1
   if lo is 0 then
     ## or whatever...
   end if
end keyUp

Tested and works.

You can enhance it by adding some automatic hiliting or
send "mouseup" etc...

Have a nice day.
