And one can Ask Emacs. This is what the Elisp manual
has to say about keywords:
A symbol whose name starts with a colon (':') is
called a keyword symbol. These symbols automatically
act as constants, and are normally used only by
comparing an unknown symbol with a few specific
alternatives. See "Variables that Never Change".
https://www.gnu.org/software/emacs/manual/html_node/elisp/Symbol-Type.html
That "Variables that Never Change" link takes you here:
https://www.gnu.org/software/emacs/manual/html_node/elisp/Constant-Variables.html
where it says this:
Function: keywordp object ¶
function returns t if object is a symbol whose
name starts with ':', interned in the standard
obarray, and returns nil otherwise.
