Should a blue-highlighted dialog box always be triggered by Return /Entry?

When I right-click on the field name box of a numeric field, select Morph>Morph Field…and enter a valid formula, the Morph button is highlighted in blue which usually suggests that a Return or Enter key will activate it. This doesn’t happen.

Is there a policy on this? My recollection is that there are a few other dialog boxes with the same issue.

Not a big deal but annoying.

Yup, that’s definitely a (minor) bug. I found some other dialog sheets with the same problem.
