+        \o  \l{Writing Code}
+
+            Writing, editing, and navigating in source code are core tasks in
+            application development. Therefore, the code editor is one of the
+            key components of \QC. You can use the code editor in the \gui Edit
+            mode.
+
+        \o  \l{Finding}
+
+            Use the incremental and advanced search to search from currently
+            open projects or files on the file system or use the locator to
+            browse through projects, files, classes, methods, documentation and
+            file systems.
+
+        \o  \l{Refactoring}
+
+            Code refactoring is the process of improving and simplifying code
+            without modifying the existing functionality of an application. You
+            can easily find and rename symbols and apply predefined actions to
+            refactor code.
+
+        \o  \l{Configuring the Editor}
+
+            You can change the fonts, colors, highlighting, and indentation.
+            If you are used to the the Vim editor, you can even run the main
+            editor in a manner similar to it in the \gui{FakeVim} mode.

+
+        \o  \l{Editing MIME Types}
+
+            \QC uses the MIME type of a file to determine which mode and editor
+            to use for opening the file. If your files do not match the
+            predefined MIME types, you can edit the MIME types.
