That's OK.  You can also drop my email address from the Cc list, and just use
"[email protected]" -- I don't do private FVWM consultancy.

It won't, but you've given me a piece of information you did not before.
Plus, my examples are just that.  I am expecting you to know enough of what I
tell you to apply it to your situation.  I can see now this is something
you're struggling with.

Aside from anything else, that's not the example I gave you, nor is it valid
FVWM syntax.  I'm fine with you asking for clarification on something, but I
do not like it when you don't put the effort in.

You have some options:


   Next (WindowName) Echo $[w.id]

This would take the next window in the ring and echo its window id.  I am
expecting you to replace "Echo" with something that uses "$[w.id]" -- the
point of the example is to show you that "$[w.id]" expands to the ID of the
specified window.

Incidentally, the output from FVWM's Echo command will go to stderr, so you
should check something like ~/.xsession-errors file to see it.
