Esc-x find
didn't appear to exist by itself,
rather it's completed with 30 varied forms.

For RMAIL in Emacs on the C-h b table of commands
<find>
appears in angle brackets, what do the angle brackets indicate?

That is Emacs notation for a keyboard key e.g. <RET>, <TAB>, <SPC>,
<DEL>, <ESC>.  Lowercase names such as <f1> or <find> refer to
function keys, which may or may not be present on any given keyboard.

"ESC x search-forward" is what you want. <find> is a key (that is
present on some keyboards).

    What does the function do?...  facemenu-set-face-from-menu

    What's a face?
    What's a facemenu?

See the "Faces" section (aka node) of the Emacs manual and the
"Stanadard Faces" node that immediately follows it.

>     What's a facemenu?

It is the prefix for the commands accessible via the Edit -> Text
Properties -> Faces menu, which are defined in the facemenu.el
file.  See the "Format Faces" node of the Emacs manual.

Correspondent = union ( author  recipient )

Enter the string that you want to search for at the prompt, then press
return.

In <C-down-mouse-2>, C means you need to hold down the control key,
mouse-2 means you press the second mouse button (while holding
Control), the down means that the event is triggered when the mouse-2
button goes down (without the "down-", mouse button events trigger
when you release the button, which is normally not what you want when
you are opening a menu).

<fc> is the name of a menu item, facemenu-set-face-from-menu is the
name of the function that is executed.

To find the answer to that,

C-h k <C-down-mouse-2> <fc> <isearch>
or C-h f facemenu-set-face-from-menu

Interactive.  isearch shows matches as you type, it does not wait
until you hit <return> like search-forward does.

Actually, it stands for incremental rather than interactive.
