non-@code{nil} (the default), but only because they are explicitly
programmed to do so.
However, if a command ends with point inside or immediately before
invisible text, the main editing loop moves point further forward or
further backward (in the same direction that the command already moved
it) until that condition is no longer true. Thus, if the command
moved point back into an invisible range, Emacs moves point back to
the beginning of that range, and then back one more character. If the
command moved point forward into an invisible range, Emacs moves point
forward up to the first visible character that follows the invisible
text.
However, if a command ends with point inside or at the boundary of invisible
text, the main editing loop moves point to one of the two ends of the invisible
text. Which end to move to is chosen based on the following factors: make sure
that the overall movement of the command is still in the same direction, and
prefer a position where an inserted char would not inherit the @code{invisible}
property. Additionally, if the text is not replaced by an ellipsis and the
command only moved within the invisible text, then point is moved one extra
character so as to try and reflect the command's movement by a visible movement
of the cursor.
Thus, if the command moved point back to an invisible range (with the usual
stickiness), Emacs moves point back to the beginning of that range. If the
command moved point forward into an invisible range, Emacs moves point forward
to the first visible character that follows the invisible text and then forward
one more character.
Incremental search can make invisible overlays visible temporarily
and/or permanently when a match includes invisible text. To enable
