Navigating via script

[David Squance]

I have a simple question about "click at the loc of ...".  I have a
navigation palette and I want a script from the main stack to 'call' one of
the buttons to move to another location.  The docs say it is possible to
simulate a mouseclick with click at the loc of btn "whatever", however they
don't say it won't work with a floating palette from another stack.  Is
this true, or have I just muffed it somewhere?
