168 ** Customize now has a new `browser' mode of traversing
169 customizations, which is in many ways easier to follow than the
170 standard one. Try it with `M-x customize-browse'.

184 ** If you set scroll-conservatively to a small number, then when you
185 move point a short distance off the screen, XEmacs will scroll the
186 screen just far enough to bring point back on screen, provided that
187 does not exceed `scroll-conservatively' lines.

189 ** Customize changes.
190
191 *** Customize has undergone a massive speedup, and should now operate
192 acceptably fast. Slowness of the interface used to be the biggest
193 gripe.
194
195 *** Many more packages have been modified to use the facility, so
196 almost all of XEmacs options can be examined through the Customize
197 groups.
198
199 *** There is a new `browser' mode of traversing customizations, in
200 many ways easier to follow than the standard one. Try it out with
201 `M-x customize-browse'.

212 you have to set `uniquify-buffer-name-style' to a legal value. 227

221 minibuffers. To use this feature, add the line: 238 minibuffers. To use this feature, add the line:

239 group (top of the customize tree). Use `M-x customize-group' to 256 Instead, it runs the command `compose-mail', which invokes the mail
240 customize settings of a specific group. 257 composition mechanism you have selected with the variable
258 `mail-user-agent'. The default choice of user agent is
259 `sendmail-user-agent', which gives behavior compatible with the old
260 behavior.
261
262 C-x 4 m now runs compose-mail-other-window, and C-x 5 m runs
263 compose-mail-other-frame.
264
265 ** When you kill a buffer that visits a file, if there are any
266 registers that save positions in the file, these register values no
267 longer become completely useless. If you try to go to such a register
268 with `C-x j', then you are asked whether to visit the file again. If
269 you say yes, it visits the file and then goes to the same position.
270
271 ** When you visit a file that changes frequently outside Emacs--for
272 example, a log of output from a process that continues to run--it may
273 be useful for Emacs to revert the file without querying you whenever
274 you visit the file afresh with `C-x C-f'.
275
276 You can request this behavior for certain files by setting the
277 variable revert-without-query to a list of regular expressions. If a
278 file's name matches any of these regular expressions, find-file and
279 revert-buffer revert the buffer without asking for permission--but
280 only if you have not edited the buffer text yourself.
