Algorithm to control bizare <XwinManager>?

[labeas]

Fortunately its easy to get N root-terminals in VT-mode;
because controlling the <XwinManager> needs more training than to land
an aircraft..
Any major <control program> should show the user WHERE YOU ARE.
 TC's only shows, after the user very carefully [to avoid capturing apps
 from other Desks] opens the <XwinManager>.
I tried to make a listing/table of the pattern of where the mouse landed
when opening the <XwinManager> from each of 6 Desks..
It seemed random/complex ?!

No we don't want absurdities like M$ or KDE with-bouncing-monkeys.
Before my systems were stolen, my preferred WindowManager was BlackBox
[now obsoluted by fluxbox] which like TC's had the <window tree
inside the mouse>, with only a small <panel> identifying the current
Desk, and taking much less area than TC's <appsMenu>..
BB's appsMenu was INSIDE-the-mouse, and non intrusive, and being a
tree, could cater for Many and rationally classified apps.

What is the trick to navigate TC's window-tree without unintentionlly
moving apps between Desks ?

Here's the start of a possible algorithm [formal description of HOW2].
The X-display-space is a 2 level tree containing:
1. one or more Desktops: D
2. zero or more Windows: W, per D.
To identify the number of the currently displayed D :.....
To examine the currently contained windows in Dn ...
To search for the D containing window:W ...
To move window:W from Dn to Dm ....
To avoid windows being unintentionally moved between Desktops, while searching the tree...
