Prevent VBScript in Custom Outlook Form From Executing

My custom Outlook form added some canned text in the message object in the Item_Open() function. Annoyingly, when I open the form in design mode, the Item_Open() is called, cluttering up the message object. It turns out that you have to hold down the Shift key when opening a form to prevent VBScript in the form from executing.

Holding down the Shift key while starting MS-Access also prevents start-up options from executing, so it is a somewhat consistent feature in MS-Office.
