No.  It echos unfinished keyboard key sequences.

Perhaps it is a platform difference.  I'm using MS Windows.  I've never seen
what you see.

And how does what it shows you tell you more about the mouse-click position than
this, which is what I see on a graphic display:

S o m e SPC T e x t <down-mouse-1> <mouse-1> C-h l

Or this, which is what I see with emacs -nw:

S o m e SPC T e x t <down-mouse-1> <mouse-movement> <mouse-1> C-h l

What is shown is not the full mouse event, with all of its position info.  All
that is shown is the name of the mouse event (including modifiers).

How do you type that?  Is M the shifted `M' key or Meta (Alt)?  If I hit the
`ESC' key and then the `[' key Emacs just tells me `M-[ is undefined'.

Customize `custom-unlispify-tag-names' to nil (off), if you want to see the real
(Lisp) names.

(IMHO that should be the default value.  It is less, not more, helpful to simply
capitalize each word and replace SPC with hyphen.  Misguided, IMO.)
