I've improved S&T2006 Keys v2.42 english and S&T2006 Keys v2.42 french a little. The run time is improved a little by removing all the comments and line breaks from the compiled script. Pressing a hot key from the Menu responds faster instead of requiring a second of time between pressing F4 and the wanted hot key.
These files are the newest files to date and should run faster than the older one linked above. I've also modified the "with GPS locater" per your suggestion. It should run on stand alone S&T2006.
Current version as of March 19, 2008 S&T|AR Keys 2008 v2.55 added hotkeys (english) S&T|AR Keys 2007 v 2.43 english S&T|AR Keys 2006 v 2.43 english S&T|AR Keys 2007 v 2.43 french / français ( for use on english versions of S&T and AutoRoute)

(only for 2006)
F11--Since true full screen doesn't exist in S&T 2006 I added in Keys 2006 a routine that will click once on each tool bar to reverse their status (to close them or open them). It will also close the GPS pane, Driving guidance, route planner and Directions. If you wish to re-open them, click on F11 and once it's done, click on F4 to select the panes you wish to open with the new added hot keys.
__________________________________________________________________________________
F4 - Added new hot keys for:
Z - GPS pane,
X - Driving guidance,
C - Route planner and
V - Directions.
WARNING: With S&T 2007 these new hot keys may crash S&T when used in full screen mode.
They are to be used only when in normal mode.

..Z...X...C..V on the keyboard should be located in the bottom left corner and the order of the icons in the tool bar menu of S&T 2006 is duplicated to make it easier to remember.

F10 -- Added a hot key for Find Nearby Places
___________________________________________________________________________________
F-6 -- Added a hot key to insert a pushpin in the center of the screen. If a user keeps the GPS position centered, the hope is this will add a pushpin close to the wanted location with a single key. Final adjustment can be made by using the up, down, left and right arrow.

Check for update is disabled since no update is planned for now (for 2006).
For now in 2007, it detects 2.42 as the latest.

Auto re-route works but please take note S&T 2006 does not take into account the vehicle's travel direction when re-routing. It will often times indicates a reverse direction when off route. Auto re-route can be disabled in the options panel. S&T2007 and later versions fixes this problem.

For users who try it please report problems you may encounter with it if any.

A new hotkey to place a pushpin on the map
I've also created a new Scanner.exe application to scan the map pane for a maroon pushpin and send 5 beeps then 1 beep every 20 seconds if it detects one. Again, please read the thread referenced above. Especially this one
POI Scanner for Microsoft Streets & Trips
v 2.42.7 Merged mod of v x.xx.6 and v x.xx.7 together.
v2.42.7 and v2.53.7 now opens the POI Scanner when starting S&T if you keep the POI Scanner in the same directory of Keys.
v 2.42.7 will disable the OSK keyboard if the operating system is Windows Vista, but leave it functioning if another OS is detected.
v 2.53.7 for S&T 2008 will leave the OSK keyboard enabled if an OS other than Windows Vista is detected.
v2.53.7 When closing S&T2008 if Keys is open, S&T2008 will want to send an error report to Microsoft. This, however does not affect it when running.
v2.55 and v2.43 Fix to the osk keyboard problem when running Vista.
