+@section A cleaner outline view
+@cindex hiding leading stars
+@cindex clean outline view
+
+Some people find it noisy and distracting that the Org-mode headlines
+are starting with a potentially large number of stars.  For example in
+the example tree from @ref{Headlines}:
+
+@example
+* Top level headline
+** Second level
+*** 3rd level
+    some text
+*** 3rd level
+    more text
+* Another top level headline
+@end example
+
+@noindent
+Unfortunately this is deeply ingrained into the code of Org-mode and
+cannot be easily changed.  You can, however, modify the display in such
+a way that all leading stars become invisible and the outline more easy
+to read.  To do this, customize the variable
+@code{org-hide-leading-stars} like this:
+
+@lisp
+(setq org-hide-leading-stars t)
+@end lisp
+
+@noindent
+and restart emacs (this is necessary to make this change effective).
+The tree then becomes
+
+@example
+* Top level headline
+ * Second level
+  * 3rd level
+    some text
+  * 3rd level
+    more text
+* Another top level headline
+@end example
+
+@noindent
+Note that the leading stars are not truly replaced by whitespace, they
+are only fontified with the face @code{org-hide} that uses the
+background color as font color.  If are are not using either white or
+black background, you may have to customize this face to get the wanted
+effect.  Another possibility is to set this font such that the extra
+stars are @i{almost} invisible, for example using the color
+@code{grey90} on a white background.
+
+Things become cleaner still if you skip all the even levels and use only
+odd levels 1, 3, 5..., effectively adding two stars to go from one
+outline level to the next:
+
+@example
+* Top level headline
+  * Second level
+    * 3rd level
+      some text
+    * 3rd level
+      more text
+* Another top level headline
+@end example
+
+@noindent
+In order to make the structure editing and export commands handle this
+convention correctly, use (again a restart of emacs will be needed)
+
+@lisp
+(setq org-odd-levels-only t)
+@end lisp
+
+@noindent
+You can convert an Org-mode file from single-star-per-level to
+double-star-per-level convention with @kbd{M-x org-convert-to-odd-levels
+RET} in that file.  It is not possible to use this setting on a
+file-local basis, so you need to decide which format to use.

+@section Using org-mode on a tty
+@cindex tty keybindings
+
+Org-mode uses a number of keys that are not accessible on a tty.  This
+applies to most special keys like cursor keys, @key{TAB} and
+@key{RET}, when these are combined with modifier keys like @key{Meta}
+and/or @key{Shift}.  Org-mode uses these bindings because it needs to
+provide keys for a large number of commands, and because these keys
+appeared particularly easy to remember.  In order to still be able to
+access the core functionality of Org-mode on a tty, alternative
+bindings are provided.  Here is a complete list of these bindings,
+which are obviously more cumbersome to use.  Note that sometimes a
+work-around can be better.  For example changing a time stamp is
+really only fun with @kbd{S-@key{cursor}} keys.  On a tty you would
+rather use @kbd{C-c .}  to re-insert the timestamp.
