I have updated Writer Guide 4.2 Chapter 16 (Customizing Writer) and
Appendix A (Keyboard Shortcuts). These files are in
http://www.odfauthors.org/libreoffice/english/writer-guide/drafts-v4.2
I'll leave them there for a few days, in case someone is available to
check my work, and then I'll publish them (they can always be
corrected and republished later, if necessary).
I haven't heard from JohnS for awhile, but it is summer holidays in
the UK so he's probably otherwise occupied. He has Chapter 12 (ToCs,
Indexes, Bibliographies) checked out.
To help get this book done, other people could check (and update as
needed) Chapters 13, 14, 15. Anyone? Be sure to (a) tell the list and
(b) put your initials in the checkout column of this page on the wiki:
