Active window and mouse location

Thanks, as always, for the responses. Getting old means you forget about the differences between Commands and Functions... but anyway
My MAIN question was whether there was a way to get LC to make a desktop window THE active, top-most window... next necessarily the LC's window (in my case) but ANY window for that matter.

I'll be using a shell command out to an AUTOHOTKEY compiled script to switch to the desired desktop window but was wondering if there was a native LC way to do so.  BTW, anyone who hasn't heard or tried AutoHotKey, should do themselves a huge favor (favour in the British colonies) and explore its capabilities... which, I assure you, are myriad on Windows platforms.  There are similar tools I have NOT explored available on the Mac.

However, before this thread evolves into a discussion about external scripting tools; please, if possible, let me know if anyone knows a LC-way to active a specific window on the desktop. ... ps... I am completely ignorant (and likely to remain so) regarding Java... so, if that is an option, I'd need a "seed" scripting suggestion as to how to start.
