Hi,

Could someone tell me how to get the effect of an "activated mark" in

transient mark mode from within elisp?  In other words, I'd like to be

able to set up the point and mark, and when my elisp completes, see

the region highlighted.  Seems like it should be simple, but nothing I

do seems to work.

You might be asking how transient mark mode works.  It seems to be just a variable that commands look at.  But this works for me:

(defun dog-test ()

  (interactive)

  (transient-mark-mode 1)

  (set-mark (point))

  (forward-char 20))

execute dog-test from the minibuffer and the current point plus 20 characters are highlighted -- basically just turn on transient mark more, set point and mark, and thats it.

HTH,
