The toggle is invoked by a fairly non-standard keyboard combination. Here is a video illustrating what I mean (</span><a href="http://www.youtube.com/watch?feature=player_detailpage&v=Y7_OZgBX8kQ#t=60" style="-webkit-text-size-adjust: auto;">http://www.youtube.com/watch?feature=player_detailpage&v=Y7_OZgBX8kQ#t=60</a><span style="background-color: rgba(255, 255, 255, 0); -webkit-text-size-adjust: auto;">), note how he switches the iMac from being the display for the MacBook to being an iMac again via keyboard shortcut (sort of off-screen). The capability, though, is done in OS X, and for the Z1, a little Windows-only program.</span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">Is there some way to get this type of support in Linux? How low level, or high level, would this type of effort be? I'm only really familiar with writing small-medium tools using Python, but I'm very interested in seeing this happen, and would like to learn more about what is, or might be, involved.</span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">Thanks,</span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="-webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">Chris</span></div></body></html>
