94 to `zap-to-char', except that it does not delete the searched-for

97 ** You can now store a number into a register with `C-u NUMBER C-x r n'

99 one, omit C-u INC), and insert it in the buffer with `C-x r g REG'.

122 ** Jamie Zawinski's `gdb-highlight' program is now distributed with
123 the `debug' package. gdb-highlight makes most objects printed in a
124 gdb buffer be mouse-sensitive: as text shows up in the buffer, it is
125 parsed, and objects which are recognized have context-sensitive
126 commands attached to them. To use it, add the following to `.emacs':

177 is unchanged. 205 is temporary and is reverted when the current command terminates, much
206 like the buffer selected by `set-buffer'. This is the same as in FSF
207 Emacs.
208
209 *** The new function `focus-frame' sets the window system focus to
210 FRAME (and selects it), regardless of the value of
211 `focus-follows-mouse'. Doing this is not well behaved, so be
212 absolutely sure that you want this.
213
214 The code that uses `select-frame' only to get the window manager focus
215 should be changed to use `set-frame-focus' instead, so that they keep
216 working when `focus-follows-mouse' is non-nil.
217
218 *** The special forms `save-selected-frame' and `with-selected-frame'
219 can now be used to temporarily change selected frame.
220
221 *** The behavior of `other-frame' command (`C-x 5 o') is unaffected by
222 these changes.

255 ** The new specifiers `vertical-scrollbar-visible-p' and
256 `horizontal-scrollbar-visible-p' may be used to control scrollbar
257 visibility. Previously, the only way to toggle scrollbar visibility
258 was to set a scrollbar's size to 0. This method is still supported
259 for backward compatibility.
260
261 ** The new specifiers `scrollbar-on-left-p' and `scrollbar-on-top-p'
262 may be used to control the position of the vertical and horizontal
263 toolbar. Previously, their position could be changed only through the
264 use of X resources.

271 ** It is now an error to change the value of a symbol whose name
272 starts with a colon, if it is interned in the standard obarray.
273
274 However, setting such a symbol to its proper value, which is that
275 symbol itself, is not an error. This is for the sake of programs that
276 support pre-19.12 XEmacs and pre-20 GNU Emacs by explicitly setting
277 these variables to themselves.

219 ** The `load-average' function now accepts a USE-FLOATS argument 285 ** The function load-average now accepts an optional argument
220 which, when non-nil, means to use floats instead of integers 286 USE-FLOATS. If it is non-nil, the load average values are returned as
221 multiplied by 100. At a future date, `load-average' will use floats 287 floating point numbers, rather than as integers to be divided by 100.
