Trapping the Delete Key

| I am working on a version of the seeker control. It is OK as long as the user just types in part of a name (the program searches a table for matching names). But I have to take into account the possibility that the user will press other keys. The backs
pace key is trapped successfully by the entryfield's onkey property, but the delete key is not. Does anyone know a way to trap the delete key?

One way would be to have onGotFocus and onLostFocus functions associated
with the entry field.
In function onGotFocus enter the line: 'On key label Del ? CHR(7)' //rings
the bell instead of deleting
In function onLostFocus enter the line 'On key'.//restores the status quo
(essential!)
