Calc- How do I click the button instead of editing it?

I have a macro tied to a button, but I can’t figure out how to activate the button. Clicking the button just highlights it for editing.

Menu Edit-Design Mode

Or if the button is really a hyperlink formatted to look like a button, then Ctrl+click.

Thank you. I feel a little less foolish now.

Leave the form editing mode:
Save your work, the close the form (or dialog).
Open again… does it work now?
