Delete key behavior for RunTempTool() with one point

[JBenghiat]

I'm using RunTempTool() to call a custom tool that inserts a plug-in.  If the user clicks the first point, then hits the delete key, the tool operation is aborted, like pressing escape.  I would like for the tool to instead go back to waiting for the first click.  Is there a way to change this behavior?

 

The tool action at this point also is kAction_OnEnterReturnKeyForToolCompletion, which makes it difficult to tell if the user has hit the delete key or the enter key.
