+If you want to view/export only selected children of your master document,
+ either because you want to save compiling time or because you want to distribut
+e single chapters of the book you are just writing, you can exclude children
+ from the output.
+ This is done via the menu
+\family sans
+Document\SpecialChar \menuseparator
+Settings\SpecialChar \menuseparator
+Child Documents
+\family default
+.
+ You can exclude\SpecialChar \slash{}
+include children by double-clicking on the
+\family sans
+include to output
+\family default
+ column of the respective child document in the list (note that this only
+ works for documents embedded via
+\begin_inset Quotes eld
+\end_inset
+
+Include
+\begin_inset Quotes erd
+\end_inset
+
+, not with
+\begin_inset Quotes eld
+\end_inset
+
+Input

+
+).
+ If the option
+\family sans
+Maintain counters and references
+\family default
+ is enabled, LyX will assure that all page numbers, references etc.
+\begin_inset space ~
+\end_inset
+
+are correct as if the whole document was processed.
+ This is useful if you want the selected sub-documents to look exactly as
+ in the context of the whole document.
+ However, LyX needs to process the whole document in the background for
+ this feature.
+ So if you want to save compile time and if counters and references do not
+ need to be correct, disable this checkbox.

+ By enabling\SpecialChar \slash{}

+ This has the advantage that it also works with Input'ed sub-documents.
+ However, counters and references will not be maintained with this approach.
