 2   A <i class="firstterm">view</i> is the jEdit term for an editor window.
 3   It is possible to have multiple views open at once, and each view can
 4   be split into multiple panes. jEdit remembers the state of open views between editing sessions.
 5  </p><p>
 6   An open file is referred to as a <i class="firstterm">buffer</i>.
 7   Unlike some editors where each buffer gets its own view, jEdit completely separates the two concepts. A buffer might be visible in several views, or none at all.
 8  </p><p>
 9   The drop-down list at the top of the view shows all open buffers; selecting one will make it visible in the view's text area. Different emblems are displayed next to buffer names in the list,
10   depending the buffer's state;
11   a red disk is shown for buffers with unsaved changes,
12   a lock is shown for read-only buffers,
13   and a spark is shown for new buffers which don't yet exist on disk.
14  </p><p>
15   As with most other graphical applications, there is a tool bar at the top of the view which provides quick access to frequently-used commands. Also, clicking the text area with the right mouse button displays a popup menu which also facilitates quick access to various commands.
16   Both the tool bar and the right-click menu can be completely customized to suit your tastes in the <span><b class="guimenu">Utilities</b></span>&gt;<span><b class="guimenuitem">Global
17   Options</b></span> dialog box; see <a href="global-opts.html#context-pane" title="The Context Menu Pane">the section called &#8220;The Context Menu Pane&#8221;</a>
18   and <a href="global-opts.html#toolbar-pane" title="The Tool Bar Pane">the section called &#8220;The Tool Bar Pane&#8221;</a>.
19  </p><p>
20   Most of the view is taken up by the text area. If you've ever used a graphical user interface before, the text area will be instantly familiar. Text can be inserted simply by typing. More details on text insertion and deletion can be found in <a href="entering-text.html" title="Inserting and Deleting Text">the section called &#8220;Inserting and Deleting Text&#8221;</a>.
21  </p><p>
22   The strip on the left of the text area is called a <i class="firstterm">gutter</i>.
23   The gutter displays marker and register locations, as well as folding arrows; it will also display
24   line numbers if the 
25   <span><b class="guimenu">View</b></span>&gt;<span><b class="guimenuitem">Line Numbers</b></span> (shortcut: <tt class="keycap">C+e C+t</tt>) command is invoked. Note this command only takes effect until the view is closed. To have line numbers visible all the time, enable the appropriate setting in the <span><b class="guilabel">Gutter</b></span> pane of the <span><b class="guimenu">Utilities</b></span>&gt;<span><b class="guimenuitem">Global Options</b></span> dialog box.
