If you type: dir -<Ctrl+Space>
PowerShell will list all available parameters below, and allow you to tab through them.
The tab completion is not static either. If you type: ps <Tab>, it will tab through all the current processes.

I didn't know about the CTR+SPACE. That being said it doesn't seem much more insightful than TAB. And no description of what the argument does.
