can happen only in the beginning, when the minor mode kicks in. Typing
@code{M-x viper-mode} will correct the situation. Viper knows about
several such minor modes and takes care of them, so the above trick
is usually not necessary. If you find that some minor mode, e.g.,

doesn't need to be harnessed.
+It is recommended to harness even those minor modes that don't override
+Viper keys, but still have their own keymaps. A general way to
+make a minor mode, @code{my-mode},
+compatible with Viper is to have the file @file{my-mode.el} include the following code:
+
+@lisp
+(when (fboundp 'viper-harness-minor-mode)

+If you don't like this feature as a default, but would still like to have

@item Vi-isms in Emacs state
Some people find it useful to use the Vi-style search key, `/', to invoke
search in modes which Viper leaves in emacs-state. These modes are:
-@code{dired-mode}, @code{mh-folder-mode}, @code{gnus-group-mode},
-@code{gnus-summary-mode}, @code{Info-mode}, and @code{Buffer-menu-mode}
+@code{dired-mode}, @code{mh-folder-mode},
+@code{Info-mode}, and @code{Buffer-menu-mode}
(more may be added in the future). So, in the above modes, Viper binds `/'
so that it will behave Vi-style. Furthermore, in those major modes, Viper
binds `:' to invoke ex-style commands, like in vi-state. And, as described
If a document consists of several files we can designate one of them as a
master and put the following at the end of that file:
@lisp
-;;; Local Variables:
-;;; eval: (viper-setup-master-buffer "file1" "file2" "file3" "file4")
-;;; End:
+;; Local Variables:
+;; eval: (viper-setup-master-buffer "file1" "file2" "file3" "file4")
+;; End:
@end lisp
@noindent
where @code{file1} to @code{file4} are names of files related to the master
focus on relevant files only.
Note that only the master file needs to have the aforementioned block of
-commands. Also, ";;;" above can be replaced by some other
+commands. Also, ";;" above can be replaced by some other
markers. Semicolon is good for Lisp programs, since it is considered a
comment designator there. For LaTeX, this could be "%%%", and for C the
above block should be commented out.
Even though these commands are sometimes useful, they are no substitute for
the powerful @emph{tag table} facility of Emacs. Viper's @kbd{:tag} command

The following two commands are normally bound to a mouse click and are part
of Viper. They work only if Emacs runs as an application under X

+already taken for other purposes in Emacs, then you should add this command

Finally, we note that Viper's Ex-style commands can be made to work on the
current Emacs region. This is done by typing a digit argument before
-@kbd{:}. For instance, typing @kbd{1:} will propmt you with something like
+@kbd{:}. For instance, typing @kbd{1:} will prompt you with something like
@emph{:123,135}, assuming that the current region starts at line 123 and
ends at line 135. There is no need to type the line numbers, since Viper
inserts them automatically in front of the Ex command.
