-Almost every \CGGI{} command has its own keyboard and mouse shortcuts. Here
-they are listed organized by window and type. If a desktop window manager and operating
-system is already using a specific key for its own purpose then that key will not be available
-for use as a shortcut in \CGG{}. An example might be the Alt key. Some specific alternatives
-are listed in~\ref{ssub:key_alternatives} in the "Key Alternatives" paragraph.
+In \CGGI{} a lot of shortcuts are defined for various operations.
+Although it is quite possible to do everything with the mouse, the extensive
+use of shortcuts can make the editing process much more convenient and
+efficient. However, with so large a variety of shortcuts it is not uncommon
+that some of them may interfere with assignments of the same shortcuts in
+the user's desktop environment, keyboard language switcher, etc. For
+example in KDE, the Alt-Tab and Shift-Alt-Tab shortcuts are commonly assigned to
+switch between different desktop applications, and if so, these keystrokes
+would not be available to \CGGI{}. Another example, in Arch linux KDE: the combination Alt+LMB does not translate the mask, but the entire Compositor window. To translate the mask we must use Ctrl+Alt+LMB.
+
+When having problems with some shortcut in \CGGI{}, it is recommended
+first to examine which set of shortcuts is assigned to the desktop
+environment and, if necessary, resolve the conflict. A special X11 application
+\texttt{xev} (or \texttt{xorg-xev}) can also help to test the keystrokes functionality (see \texttt{man xev}).
+Otherwise, \CGGI{} is completely desktop-neutral and has no
+requirements of some special window manager's support.
