Since the default input is the current directory, this has the effect
of specifying the current directory. Normally that means to visit the
too. If you want to use just plain `*' as a wildcard, type `*""'; the
doublequotes make no difference in the shell, but they prevent
special treatment in `dired-do-shell-command'.

+position of the underline. When set, it overrides the
+`x-use-underline-position-properties' variables.

*** The new face `mode-line-inactive' is used to display the mode line
of non-selected windows. The `mode-line' face is now used to display
horizontally or vertically, a saved window configuration is restored,
or when the frame is resized.
++++
+*** The %c and %l constructs are now ignored in frame-title-format.
+Due to technical limitations in how Emacs interacts with windowing
+systems, these constructs often failed to render properly, and could
+even cause Emacs to crash.
+
++++

+will expand as needed, but not contract automatically. To contract
+the tool bar, you must type C-l.

+*** New option `ebnf-arrow-extra-width' which specify extra width for arrow
+shape drawing.
+The extra width is used to avoid that the arrowhead and the terminal border
+overlap. It depens on `ebnf-arrow-shape' and `ebnf-line-width'.

+*** Font-Lock mode: in major modes such as Lisp mode, where some Emacs
+features assume that an open-paren in column 0 is always outside of
+any string or comment, Font-Lock now highlights any such open-paren in
+bold-red if it is inside a string or a comment, to indicate that it
+can cause trouble. You should rewrite the string or comment so that

*** New standard font-lock face `font-lock-preprocessor-face'.
jit-lock-context-time determines the delay after which contextual
refontification takes place.

+*** lazy-lock is considered obsolete.
+
+The `lazy-lock' package is superseded by `jit-lock' and is considered
+obsolete. `jit-lock' is activated by default; if you wish to continue

*** The new command `revert-buffer-with-coding-system' (C-x RET r)
`comint-use-prompt-regexp'. The old name has been kept as an alias,
but declared obsolete.
++++
+*** The new INSIDE_EMACS environment variable is set to "t" in
+subshells running inside Emacs. This supersedes the EMACS environment
+variable, which will be removed in a future Emacs release. Programs
+that need to know whether they are started inside Emacs should check

-Basically, it uses two function keys (default F3 and F4) like this:
+Keyboard macros are now defined and executed via the F3 and F4 keys:

* Changes in Specialized Modes and Packages in Emacs 22.1:
+** Changes in Shell Mode
+
+*** Shell output normally scrolls so that the input line is at the
+bottom of the window -- thus showing the maximum possible text. (This
+is similar to the way sequential output to a terminal works.)
+
** Changes in Dired
+++

point, mark some image files in a dired buffer and do C-t d to display
thumbnails of them in a separate buffer.
buffers and no warning will be issued (for compatibility with the
behavior in older versions of Emacs).
+---
** Changes in Allout
+*** Some previously rough topic-header format edge cases are reconciled.
+Level 1 topics use the mode's comment format, and lines starting with the
+asterisk - for instance, the comment close of some languages (eg, c's "*/"
+or mathematica's "*)") - at the beginning of line are no longer are
+interpreted as level 1 topics in those modes.
+
+*** Many or most commonly occuring "accidental" topics are disqualified.
+Text in item bodies that looks like a low-depth topic is no longer mistaken
+for one unless its first offspring (or that of its next sibling with
+offspring) is only one level deeper.
+
+For example, pasting some text with a bunch of leading asterisks into a
+topic that's followed by a level 3 or deeper topic will not cause the
+pasted text to be mistaken for outline structure.
+
+The same constraint is applied to any level 2 or 3 topics.
+
+This settles an old issue where typed or pasted text needed to be carefully
+reviewed, and sometimes doctored, to avoid accidentally disrupting the
+outline structure. Now that should be generally unnecessary, as the most
+prone-to-occur accidents are disqualified.
+
+*** Allout now refuses to create "containment discontinuities", where a
+topic is shifted deeper than the offspring-depth of its container. On the
+other hand, allout now operates gracefully with existing containment
+discontinuities, revealing excessively contained topics rather than either
+leaving them hidden or raising an error.
+
*** Topic cryptography added, enabling easy gpg topic encryption and
decryption. Per-topic basis enables interspersing encrypted-text and
clear-text within a single file to your heart's content, using symmetric
and/or public key modes. Time-limited key caching, user-provided
symmetric key hinting and consistency verification, auto-encryption of
pending topics on save, and more, make it easy to use encryption in
-powerful ways.
-
-*** `allout-view-change-hook' marked as being deprecated - use
-`allout-exposure-change-hook' instead. Both are currently being used, but
-`allout-view-change-hook' will be ignored in a subsequent allout version.
-
-*** Default command prefix changed to "\C-c " (control-c space), to avoid
-intruding on user's keybinding space. Customize the
+powerful ways. Encryption behavior customization is collected in the
+allout-encryption customization group.
+
+*** Navigation within an item is easier. Repeated beginning-of-line and
+end-of-line key commands (usually, ^A and ^E) cycle through the
+beginning/end-of-line and then beginning/end of topic, etc. See new
+customization vars `allout-beginning-of-line-cycles' and
+`allout-end-of-line-cycles'.
+
+*** New or revised allout-mode activity hooks enable creation of
+cooperative enhancements to allout mode without changes to the mode,
+itself.
+
+See `allout-exposure-change-hook', `allout-structure-added-hook',
+`allout-structure-deleted-hook', and `allout-structure-shifted-hook'.
+
+`allout-exposure-change-hook' replaces the existing
+`allout-view-change-hook', which is being deprecated. Both are still
+invoked, but `allout-view-change-hook' will eventually be ignored.
+`allout-exposure-change-hook' is called with explicit arguments detailing
+the specifics of each change (as are the other new hooks), making it easier
+to use than the old version.
+
+There is a new mode deactivation hook, `allout-mode-deactivate-hook', for
+coordinating with deactivation of allout-mode. Both that and the mode
+activation hook, `allout-mode-hook' are now run after the `allout-mode'
+variable is changed, rather than before.
+
+*** Default command prefix was changed to "\C-c " (control-c space), to
+avoid intruding on user's keybinding space. Customize the
`allout-command-prefix' variable to your preference.
-*** Allout now uses text overlay's `invisible' property (and others) for
-concealed text, instead of selective-display. This simplifies the code, in
-particular avoiding the need for kludges for isearch dynamic-display,
-discretionary handling of edits of concealed text, undo concerns, etc.

- auto-fill-mode is now left inactive when allout-mode starts, if it

configuration variable makes it easy to disable auto fill in allout
outlines in general or on a per-buffer basis.
- - new hook `allout-mode-deactivate-hook', for coordinating with

+`display-mm-height' and `display-mm-width'.
+
** Mouse pointer features:
+++ (lispref)
property over the second half of the command to force (deferred)
refontification of `bar' whenever the `e' is added/removed.
+*** `font-lock-extend-region-functions' makes it possible to alter the way
+the fontification region is chosen. This can be used to prevent rounding
+up to whole lines, or to extend the region to include all related lines
+of multiline constructs so that such constructs get properly recognized.
+
** Major mode mechanism changes:
+++
-*** `set-auto-mode' now gives the interpreter magic line (if present)
-precedence over the file name. Likewise an `<?xml' or `<!DOCTYPE'
-declaration will give the buffer XML or SGML mode, based on the new
-variable `magic-mode-alist'.
+*** If new variable `auto-mode-case-fold' is set to a non-nil value,
+Emacs will perform a second case-insensitive search through
+`auto-mode-alist' if the first case-sensitive search fails.
+This means that a file FILE.TXT is opened in text-mode, and a file PROG.PY
+is opened in python-mode. Note however, that independent of this
+setting, *.C files are usually recognized as C++ files.
+It also has no effect on systems with case-insensitive file names.
+
++++
+*** New variable `magic-mode-alist' determines major mode for a file by
+looking at the file contents. It takes precedence over `auto-mode-alist'.
+
++++
+*** An interpreter magic line (if present) takes precedence over the
+file name when setting the major mode.
+
++++
+*** XML or SGML major mode is selected when file starts with an `<?xml'
+or `<!DOCTYPE' declaration.
+++
*** Use the new function `run-mode-hooks' to run the major mode's mode hook.
*** `emacsserver' now runs `pre-command-hook' and `post-command-hook'
when it receives a request from emacsclient.
++++
+*** `current-idle-time' reports how long Emacs has been idle.
+
** Lisp file loading changes:
