I used the mouse to click the button labelled "Save for Future Sessions".

"C-h k" followed by a click on that button shows documentation for
widget-button-click -- not very helpful.  C-h k RET with point on the
button just shows docs for Custom-newline -- also not very helpful.

Finally I figured out that M-x describe-char followed by
middle-clicking on 'push-button', followed by left-clicking the
'[show]' text next to :action, shows:

#[(widget &optional event)
  "\300 \207"
  [Custom-save]
  1]

I found this sequence extremely obscure.

Apparently Custom-save calls custom-save-all.
But, when I evalled (custom-save-all) by hand, it only asked once.
