[Lazarus] Displaying system menu

[Mark Morgan Lloyd]

Is there an easy and portable way of telling a form to display its 
system menu, for example in rsponse to a right-click? I'm trying to do 
something without border etc. (to suppress all sizeability and the title 
bar) but still want an easy way of moving it.

Is there an easy and portable way of extending the system menu with e.g. 
an entry to pop up an "about" box?

Apologies if these are FAQs, I'm still trying to get to grips with the 
documentation.
