>I do want to do this at design time, am not sure how to use the setall() at design time in the command window.

Next to the manual multi-select solution, you can also do it programmatically, for instance when there are controls inside containers so that you cannot multi-select all of them:
- in the Form Designer, highlight any form.member, say "Text1" or so,
- and then in the Command Window:

ASELOBJ(laForm,1)
laForm[1].SetAll('Anchor',240)
