Is there some way to know if the shift key is down .... when the focus is on a different form?

Background: from within my PEMEditor tool, which works when using either the Form or Class Designer, I want to know when the user has held the shfit key while using the designer (presumably for selecting multiple objects).

Thus, normal techniques of capturing key movements or mouse movements are irrelevant, since these events are not occurring on my form.

Thanks in advance.
