Package: emacs
Version: 23.3.1
When keymap text property is set, it changes key binding for one
character after the region it is set to. The following code
demonstrates the problem:
(let ((map (make-sparse-keymap)))
(define-key map (kbd "RET") 'bug)
(switch-to-buffer "test")
(insert "123456")
(put-text-property 1 4 'keymap map)
(goto-char 4)
(message "keymap: %s"
(get-text-property (point) 'keymap)) ; no keymap property here
(message "key-binding: %s"
(key-binding (kbd "RET")))) ; but the key binding is changed
Regards,
Dmitry

No: in your case, the text property covers characters between positions
1 to 4, and point is at position 4 (right in front of the char at
position 4 and right after the char at position 3), i.e. right on the
boundary of the text-property. When on the boundary, the behavior will
depend on whether the property is sticky or not, so you can control it
by twiddling the "front-advance, read-advance" settings of your overlays
or the rear-non-stick and front-sticky text-properties.
