The following info node explains the point-left and point-entered text
properties:

    (elisp)Special Properties

I found it like this:

M-x apropos RET point.*hook RET

This mentioned a variable inhibit-point-motion-hooks.  The
documentation of this variable mentions the point-left and
point-entered text properties.

So I went to the elisp info file (Emacs Lisp Reference), hit the i key
to search the index and entered point-left as the search string.
