How can I pop up File Structure for any class where cursor is?

Hi,

Currently when I hit CTRL+F12, it will shows popup of the current class File Structure. I like this feature alot!

However, when I browse source, I would like to see the File Structure of other classes used in the current source file. Currently I have to first jump into the interested class's source first then hit CTRL+F12 again to see this. It would be nice that CTRL+F12 can popup any arbitrary class where my cursor is (much like the CTRL+H, but unfortunately it doesn't shows Class members with this) without have to jump to source first. Is there way to do this?

Thanks,

Zemian
