HandlerUtil getSelection methods [message #484734]

A HandlerUtil is often used to extract info from an ExcutionEvent during
command handler execution. The API docs list two methods in particular:

- getCurrentSelection
- getShowInSelection

What's the difference? The latter's description mentions a
ShowInContext selection. But I can't determine what this means.

After some more playing around, the former seems to be where the mouse
was pointing at the moment of the right-click. The later seems to be
where the cursor was.

I don't think that this is the correct interpretation. "ShowInContext"
has a special meaning for parts, see

http://wiki.eclipse.org/FAQ_How_do_I_make_my_view_appear_in_ the_Show_In_menu%3F

So my assumption is, that by quereing getShowInSelection() you will only
catch current selections from parts that implement IShowInSource.

Thanks for the link, Dan. I wasn't even aware of such a feature.
