Thanks for the info.
I have been looking at VBScript (already in Windows) & AutoHotKeys.
VBScript handles most keys EXCEPT the Win key which I need (Win+Tab). AutoHotKeys does handle the Win key so I am leaning that way.

Here is what I am currently up to.
I have combined all my Opus Toolbar commands into the Windows 7 TaskBar (SEE: attached JPEG). Everything runs just great there EXCEPT Opus Menu items such as the yellow Opus shell icon & the round green Windows flag... they won't load my custom menus so I need to do it with HotKeys. That is why I am interested in this topic (plus the BIG red X as mentioned before).

As an aside, it might make more sense to start a CoffeeShop thread/diary of this Start Menu replacement that you are setting up, instead of spreading snapshots of the progress through lots of different threads on the forum.
Then anyone who is interested in following the progress can follow it in one nice, chronological thread, and all the other threads can stay on topic instead of all of them drifting back to the topic of your start menu replacement project. 
I don't recall ever mentioning my START Menu replacement project anywhere on this thread. In fact, this thread has nothing to do with the START Menu project (which is on hold) at all ; it has to do with some problems I ran into converting my Opus Toolbar to the Windows Taskbar and I am simply trying to get help on that one topic.
But... now that you mentioned it, tell me about the CoffeShop; it sounds interesting. From what I am hearing you say, the CoffeShop does not have the one topic per thread limit that Help & Support has.
Does it get as much attention from you guys as Help & Support or does it relay more on user-to-user support or both?
I do like the idea of having a single thread for a general topic like my START Menu project (when I get back to it), that would be very nice indeed. That would provide a community oriented approach to solving problems which would bring in more new ideas. NEAT.
Thanks for the heads up;

Hi Leo,
Your suggestion about using AutoHotKey was pretty close.
I made a couple of changes like this...
Send #{Tab} <- Win+Tab ALWAYS front focuses the last used Window (just what I wanted).
Sleep, 5 <- Did not need as much sleep delay as first expected, anything over 1ms worked.
Send !{F4} <- Alt+F4 closes the last active Window (PERFECT).
Also, I can keep pressing the BIG red X and it will close the next on-top Window. I have had 10 Windows open and pressing the BIG red X closes them all (one at a time).
AutoHotKey did the trick... PERFECTLY.
Thanks for the suggestion.

I may end up modifying the above AutoHotKey script as it does work perfectly when the BIG red X is in the Windows TaskBar (where I want it) BUT, when the X is in the Opus toolbar it closes the toolbar. Something more to ponder over.
This is another reason why I wanted to move all my Opus Toolbar items to the Windows TaskBar; it is pretty hard to close the TaskBar without running a utility such as StartKiller.
I think the Opus Toolbar closing can also be resolved, I will sleep on it (ZZZZzzzz).
Doc
Just discovered a nice side-benefit to the AutoHotKey close current window command... it closes ONLY OPEN windows and ignores minimized windows on the TaskBar; how neat is that?

Okay, your Start Menu / Taskbar / Toolbar / etc. project(s). There's a big screenshot of it just above. 
It's getting confusing as someone browsing the forum is going to see all these threads/screenshots and think that is what Opus looks like or does, when it's quite a niche aspect of Opus and has been highly customized. (Or in the above case isn't even Opus, which confused me at first as the screenshot looks very similar to the toolbar you posted in several other threads. If I'm getting confused about what is and isn't Opus, other people definitely will be.)
It's fine to ask for help about using other programs, but please use the CoffeeShop area when you do.
We like to keep the Help & Support area just for questions about Opus. That way it is more useful to other people who come here looking for help about Opus.
From the front page:
Help & Support: Post your Directory Opus questions here.
CoffeeShop: Discuss anything you like with other forum members.
CoffeeShop is like the "General Discussion" area you've probably seen on other forums.
We read every post in every forum.
However, we're here to help people use Opus, not so much to provide free tech support for Windows and any other software you may happen to use (except when it comes to making Opus work together with that software), so we're less likely to respond to non-Opus questions. If we can help with a quick answer then we will, but we're obviously already very busy writing & supporting Opus itself, which is what we're paid to do; helping with other stuff is purely a spare-time thing (and doing Opus often eats into our spare time already ). And we often just don't know the answer when it comes to other programs, since we're not experts in them like we are with Opus.
