Hi Ihor,

thanks, good idea! A few days ago I had a similar idea, but mine
was worse... I found, by running this,

  (find-orggrep "grep --color=auto -nH --null -e read-char-exclusive *.el")

that `read-char-exclusive' appears in 29 places in the Org
source, and I was thinking of replacing some of them by a
`my-read-char-exclusive', and then set a breakpoint in
`my-read-char-exclusive'...

I have just tried running this in an Org file,

  (debug-on-entry        'read-char-exclusive)
  (eek "C-c C-e")
  (cancel-debug-on-entry 'read-char-exclusive)

and after running the first two sexps above with my favorite
variant of `C-x C-e' the backtrace showed me that this

  (find-efunction 'org-export--dispatch-action "read-char-exclusive")

is the occurrence that matters - the one inside
`org-export--dispatch-action'. I'll play more with that
soon!

  Cheers =),
