The other special commands of outline mode are used to make lines visible
or invisible. Their names all start with
Most of them fall into pairs of opposites. They are not undoable; instead,
you can undo right past them. Making lines visible or invisible is simply
not recorded by the undo mechanism.
Many of these commands act on the “current” heading line. If point is on a heading line, that is the current heading line; if point is on a body line, the current heading line is the nearest preceding header line.
Two commands that are exact opposites are C-c C-c
hide-entry) and C-c C-e (
show-entry). They apply
to the body lines directly following the current heading line.
Subheadings and their bodies are not affected.
Two more powerful opposites are C-c C-d (
and C-c C-s (
show-subtree). Both apply to the current
heading line's subtree: its body, all its subheadings, both
direct and indirect, and all of their bodies. In other words, the
subtree contains everything following the current heading line, up to
and not including the next heading of the same or higher rank.
Intermediate between a visible subtree and an invisible one is having
all the subheadings visible but none of the body. There are two
commands for doing this, depending on whether you want to hide the
bodies or make the subheadings visible. They are C-c C-l
hide-leaves) and C-c C-k (
A little weaker than
show-branches is C-c C-i
show-children). It makes just the direct subheadings
visible—those one level down. Deeper subheadings remain invisible, if
they were invisible.
Two commands have a blanket effect on the whole file. C-c C-t
hide-body) makes all body lines invisible, so that you see just
the outline structure (as a special exception, it will not hide lines
at the top of the file, preceding the first header line, even though
these are technically body lines). C-c C-a (
makes all lines visible. These commands can be thought of as a pair
of opposites even though C-c C-a applies to more than just body
The command C-c C-q (
hide-sublevels) hides all but the
top level headings. With a numeric argument n, it hides everything
except the top n levels of heading lines.
The command C-c C-o (
hide-other) hides everything except
the heading and body text that point is in, plus its parents (the headers
leading up from there to top level in the outline) and the top level
When incremental search finds text that is hidden by Outline mode, it makes that part of the buffer visible. If you exit the search at that position, the text remains visible. You can also automatically make text visible as you navigate in it by using M-x reveal-mode.blog comments powered by Disqus
