    <p>I work on a project called <a href="http://code.google.com/p/uawks/" rel="nofollow noreferrer">UAWKS</a> (Unofficial Apple Wireless Keyboard Support) that helps Windows users use Apple's bluetooth keyboard. One of the main goals of UAWKS is to swap the <kbd>Cmd</kbd> key (which behaves as <kbd>Winkey</kbd> in Windows) with <kbd>Ctrl</kbd>, allowing users to do <kbd>Cmd</kbd>+<kbd>C</kbd> for copy, <kbd>Cmd</kbd>+<kbd>T</kbd> for new tab, etc.</p> <p>It is currently developed using <a href="http://www.autohotkey.com" rel="nofollow noreferrer">AutoHotkey</a>, which worked pretty well under Windows XP. However, on Vista and Windows 7, <kbd>Cmd</kbd>+<kbd>L</kbd> causes problems:</p> <ul> <li>Regardless of low-level keyboard hooks, <kbd>Win</kbd>+<kbd>L</kbd> is always intercepted by Windows and normally locks the workstation...</li> <li>You can disable workstation locking with <a href="http://www.howtogeek.com/howto/windows-vista/disableenable-lock-workstation-functionality-windows-l/" rel="nofollow noreferrer">this registry hack</a>, but pressing <kbd>Win</kbd>+<kbd>L</kbd> still can't be rebound in AHK</li> <li>Pressing <kbd>Win</kbd>+<kbd>L</kbd> leaves Winkey in the Keydown state until the next (additional) Winkey Up. Simulating a Keyup event doesn't seem to work either!</li> </ul> <p>It seems that <kbd>Win</kbd>+<kbd>L</kbd> is a special chord that messes everything else up.</p> <p>I've looked through the AHK source code, and they try to address this problem in <code>SendKey()</code> in keyboard_mouse.cpp (near line 883 in v1.0.48.05), but it doesn't work. I wrote up my own low-level keyboard hook application in C#, and I see the same problem.</p> <p>Has anyone else run into this? Is there a workaround?</p>

    1. COI should add that there are forum posts at AutoHotkey.com, but the solutions are either outdated or incorrect (see below). Also, my question is not really limited to AutoHotkey. I eventually want to re-implement the whole program in C#. This is more a question about how Windows Vista and Windows 7 treat Winkey+L differently, and if anyone has seen/solved this before. http://www.autohotkey.com/forum/viewtopic.php?t=27554&highlight=winkey http://www.autohotkey.com/forum/viewtopic.php?t=15513&postdays=0&postorder=asc&start=0

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
