Editors</h3>
<p class="Para"> Depending on the type of file that is being edited, the appropriate
editor is displayed in the editor area. For example, if a .TXT file is being
edited, a text editor is displayed in the editor area. The figure below shows
an editor open on the file file1.txt. The name of the file appears in the tab
of the editor. An asterisk (*) appearing at the left side of the tab indicates
that the editor has unsaved changes. If an attempt is made to close the editor
or exit the Workbench with unsaved changes, a prompt to save the editor's changes
will appear.</p>

</p>
<p class="Para">When an editor is active, the Workbench menu bar and toolbar contain
operations applicable to the editor. When a view becomes active, the editor
operations are disabled. However, certain operations may be appropriate
in the context of a view and will remain enabled.</p>
<p class="Para"> The editors can be stacked in the editor area and individual
editors can be activated by clicking the tab for the editor. Editors can also
be tiled side-by-side in the editor area so their content can be viewed simultaneously.
In the figure below, editors for JanesFile.txt and JanesFile2.txt have been placed
above the editor for JanesText.txt. Instructions will be given later in this tutorial explaining
how to rearrange views and editors.</p>

</p>
<p>If a resource does not have an associated editor, the Workbench
will attempt to launch an external editor registered with the platform. These
external editors are not tightly integrated with the Workbench and are not embedded
in the Workbench's editor area. </p>
<p>Editors can be cycled through using the back and forward arrow buttons
in the toolbar. These move through the last mouse selection points and permit moving through several points
in a file before moving to another one. Additionally, editors can be cycled by using
the Ctrl+F6 accelerator (Command+F6 on the Macintosh). Ctrl+F6 pops up a list of currently
open editors. By default, the list will have selected the editor used before the current one, allowing
you to easely go back to the previous editor.

On Windows, if the associated editor is an external editor, the Workbench may attempt
to launch the editor in-place as an
OLE document editor. For example, editing a DOC file will cause Microsoft Word
to be opened in-place within the Workbench if Microsoft Word is installed on
the machine. If Microsoft Word has not been installed, Word Pad will open instead.</p>
