What does the NEWS file have to do with the menus at the top?

The NEWS file is divided into sections.  You can just skip the Lisp
stuff.  Here is the part about the toolbar.  I found it by searching
for "tool" in the NEWS file.

| ** Tool bar support.
| Emacs supports a tool bar at the top of a frame under X.  For details
| of how to define a tool bar, see the page describing Lisp-level
| changes.  Tool-bar global minor mode controls whether or not it is
| displayed and is on by default.  The appearance of the bar is improved
| if Emacs has been built with XPM image support.  Otherwise monochrome
| icons will be used.
| To make the tool bar more useful, we need contributions of extra icons
| for specific modes (with copyright assignments).

It says that "tool-bar global minor mode" allows you to turn it off.
What's a minor mode?  I do C-h i d m Emacs RET to open the Emacs
manual, then type i for an index search, then "minor mode" as the
search string.  This gives me a couple of false positives, but just
hitting comma (as instructed) finally brings me to the node
"(emacs)Minor Modes" which has the following:

|    Minor modes are optional features which you can turn on or off.  For
| example, Auto Fill mode is a minor mode in which <SPC> breaks lines
| between words as you type.  All the minor modes are independent of each
| other and of the selected major mode.  Most minor modes say in the mode
| line when they are on; for example, `Fill' in the mode line means that
| Auto Fill mode is on.
|    Append `-mode' to the name of a minor mode to get the name of a
| command function that turns the mode on or off.  Thus, the command to
| enable or disable Auto Fill mode is called `M-x auto-fill-mode'.  These
| commands are usually invoked with `M-x', but you can bind keys to them
| if you wish.  With no argument, the function turns the mode on if it was
| off and off if it was on.  This is known as "toggling".  A positive
| argument always turns the mode on, and an explicit zero argument or a
| negative argument always turns it off.

So, M-x auto-fill-mode RET turns on (or off) auto fill mode.  So what
is the command for turning on (or off) tool-bar mode?

What does the tool-bar have to do with define-key statements?
