Yes, they can. I don't remember exactly how, but after altering some settings (perhaps it was in gconf-editor) you can indeed use Super-L and Super-R with other keys. However! As soon as you do, you can no longer use it on it's own. In other words the Super-L and Super-R keys behave like CTRL or ALT or SHIFT and when pressed by themselves do nothing.
A Windows Compatibility Mode checkbox would be nice. A setting somewhere that does the following:
1. Opens menu with Super (either SuperL or SuperR).
2. Opens Run command with Super - R.
3. Show desktop with Super - D.
4. Open Nautilus with Super - E (or N, whichever you prefer).
5. Search with Super - F
6. Lock screen with Super - L.
Heck, I'd settle for a config file that I had to edit to get this feature. This setting does not have to be on by default, but it would go a long way in making Linux more productive.
