Following is quick fix:

*** List.Init event
this.additem("q1")
this.additem("q2")
this.additem("\q3"+space(3))
this.additem("q4")
*** List.Keypress event
LPARAMETERS nKeyCode, nShiftAltCtrl
if nKeycode=5 or nKeycode=24
 this.tag=this.value
endif
*** List.Interactivechange event
if empty(right(this.value,3))
 this.value=this.tag
 this.tag=""
endif
