window-numbering-face doesn't work

[VladimirAlexiev]

https://github.com/nschum/window-numbering.el/blob/master/window-numbering.el#L177:
window-numbering-face should not be quoted.

Also: is it possible to add a tooltip there? Eg "Use Alt-# to select window" .

Huh? window-numbering-face isn't a variable. If I didn't quote it, there'd be a "void-variable" error.

[VladimirAlexiev]

Right! My head was screwed wrongly.
It won't hurt to give an example in the docstring, eg "Set it like this

(defface window-numbering-face '((default :foreground "red" :weight bold))
         "Face for window number in the mode-line.")

BTW the elisp manual sec 37.12.2 Defining Faces says:

• Macro: defface face spec doc [keyword value]…
  This macro declares FACE as a named face whose default face spec is
  given by SPEC. You should not quote the symbol FACE, and it should
  not end in ‘-face’ (that would be redundant)
