CDS Attribute for mouse click.

I came across this CDS attribute on the MEDITECH-L.

IFE=IF{@Z.lastkey=@Z.mouse.click 1,
IFE=P(R,S,"X"^/[ANS%0,"Z.C1"]|0)^#;1}

Where "Z.C1" is the name of the query on the CDS, and "X" being the input added to a field that is clicked with the mouse.

I can see this being used for a few different things.  

1. We are going live with electronic ordering by doctors, and to minimize on the amount of time they must spend entering data on a patient we could use this for check boxes. E.g. for MRI

2. We have a wound identification screen that clicking would be much faster than entering all the way through it.
