  9   Any changes made in this dialog box are lost after the buffer is
 10   closed.

 35  <para>
 36   Buffer-local properties provide an alternate way to change editor settings
 37   on a per-buffer basis. While changes made in the Buffer Options dialog box
 38   are lost after the buffer is closed, buffer-local properties take effect
 39   each time the file is opened, because they are embedded in the file
 40   itself.
 41  </para>
 42  <para>
 43   When jEdit loads a file, it checks the first and last 10 lines for
 44   colon-enclosed name/value pairs. The following example changes
 45   the indent width to 4 characters, enables soft tabs, and sets
 46   the buffer's edit mode to Perl:
 47  </para>
 48  <screen>:indentSize=4:noTabs=true:mode=perl:</screen>
 49  <para>
 50   Note that adding buffer-local properties to a buffer only
 51   takes effect after the next time the buffer is loaded.
 52  </para>
 53  <para>
 54   The following table describes each buffer-local property in detail.

142   displays the global options dialog box. The dialog box is divided into
143   several panes, each pane containing a set of related options. Use the list
144   on the left of the dialog box to switch between panes. Only panes
145   created by jEdit are described here; some plugins add their own option
146   panes, and information about them can be found in the documentation
147   for the plugins in question.
148  </para>

196   first lines of buffers will be matched against to determine the edit mode.
197  </para>
198  <para>

200   merely writes values to the user properties file which override those
201   in mode files. To find out how to edit mode files directly, see

273   contains two option panes, <guibutton>General</guibutton> and
274   <guibutton>Colors</guibutton>. Both of these option panes should be
275   self-explanatory. See <xref linkend="vfs-browser" />
276   for more information.
277  </para>
278 </sect1>
279 <sect1 id="settings-directory"><title>The jEdit Settings Directory</title>
280  <para>
281   jEdit stores all settings, macros, and so on as files
282   inside its <firstterm>settings directory</firstterm>. In most cases, editing
283   these files is not necessary, since graphical tools and commands can do the
284   job. However, being familiar with the structure of the settings directory
285   still comes in handy
286   in certain situations, for example when you want to copy jEdit settings
287   between computers.
288  </para>
289  <para>
290   The location of the settings directory is system-specific; it is printed to
291   the activity log (<guimenu>Utilities</guimenu>&gt;<guimenuitem>Activity
292   Log</guimenuitem>). For example:
293  </para>
294  <screen>[message] jEdit: Settings directory is /home/slava/.jedit</screen>
295  <para>
296   Specifying the <command>-settings</command> switch on the command line
297   instructs jEdit to store settings in a different directory.
298   For example, the following command will instruct jEdit to
299   store all settings
300   in the <filename>jedit</filename> subdirectory of the <filename>C:</filename>
301   drive:
302  </para>
303  <screen><prompt>C:\jedit&gt;</prompt> <userinput>jedit -settings=C:\jedit</userinput></screen>
304  <para>
305   The <command>-nosettings</command> switch will force jEdit to not look for
306   or create a settings directory. Default settings will be used instead.
307  </para>
308  <para>
309   If you are using <application>jEditLauncher</application>
310   to start jEdit on Windows, these parameters cannot be specified on the
311   MS-DOS prompt command line when starting jEdit; they must be set as described
312   in <xref linkend="launcher-starting" />.
313  </para>
314  <para>
315   jEdit creates the following files and directories
316   inside the settings directory; plugins may add more:
317  </para>
318  <itemizedlist>
