Index entries should preferably use only lower-case letters, to avoid
problems with sorting index entries in different locales.

In addition, I would rephrase the above index entry to say just

  @cindex window tool bar

> +@findex global-window-tool-bar-mode
> +@vindex global-window-tool-bar-mode

This will create two identical index entries (since we produce a
single Index from all the index entries).  So leave just one of the
two.

This paragraph left me puzzled.  By default, the frame-global tool bar
follows the major mode of the selected buffer's window.  This is not
going to change even under global-window-tool-bar-mode, is it?  If so,
when will the window-specific tool bar be displayed -- only in
non-selected windows whose buffers have a major mode different from
that of the selected-window's buffer?  If so, this should be
explicitly explained in the manual, I think.

Also, does this mean the window-specific tool bar will appear and
disappear depending on which window is selected?  Wouldn't that cause
annoying "flickering" of display?

Are these window tool bars also limited to windows whose buffers'
major mode is different from the selected window?  In any case, this
aspect, whether identical to global-window-tool-bar-mode or different
from it, should be explicitly documented.

Last, but not least: please mention the bug number in the commit log
message.


Thanks.
