Forums Scripts & Popups dialog - key press

if i have txt box on form, how can i make when i write something into it that when i press enter that same action happens as when i press some button (button1 for example)?

i think it's -f, make a button the default action. (/did)

didnt understund
how will mirc known that i pressed ENTER button ?
and how to call a buton1 on enter?

Following on from this question....

How can I get mirc to detect the enter key being pressed?
I dont want to have a button in the dialog, but I want it to continue to the next dialog upon pressing the Enter key.

Is this possible?
