Custom properties of IDE palettes?

[Geoff Canyon]

I'm exploring the LC 8 IDE. If I type in the message box:

put the customkeys of the mouseStack

and put the pointer over the message box, I press return and see a list of
custom properties:

cREVIntelligenceObject
cREVLeft
cREVTopLeft
etc....

But if I put the pointer over the Tools palette or the Properties palette,
I get nothing. It's not a mouseStack issue; I can put the name of the
mouseStack and get "revPropertyInspector 1". And this doesn't work either:

lock messages;put the customkeys of stack "revPropertyInspector 1"

Any ideas?
