I think the biggest annoyance was "the same keys" (at least to me). Maybe a more UNIX like combination will ease the pain?
What would you suggest? We should be careful of changing this just so that it is different from Windows though, as it not only introduces confusion in users who need to use both systems, but also smacks of "Not Invented Here" syndrome. :-)
And a text modification, which hints to the "information, why" and the "way to deactivate, if save"..
This is a good idea. There seems to be a lot of user confusion over the role of the SAK in system security, and this should be addressed somewhere in the control center or other configuration dialog(s).
What about to hadle it all in the first setup run (setup wizard was the name?) by adding a dialoge, which offers 1. extra information button (which explains the use and maybe some sort of save to deaktivate, if your whole users in the network are trusted ones?) and 2. a radio Button for the "style" unix or win (there was a sgi combination for the x-server reset, alt+backspace+f12 or something.)
