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.
