DOUBLE CLICK CHECK BOX IN FIELD ATTRIBUTE

Hi all....

we are having one check box in the the field attributes of layout screen... that is ...

RESPONDS TO DOUBLE CLICK.

my doubt is how to give functionality to that if i checked it in layout... and where...

for example....

I checked it for one text field... in layout named by NOTE...

So if i click that text in screen while working... can i get some information window like that... otherwise what is the perpose of that...

Thank you,
