I tried to reproduce this problem, and typed 'C-h C-h' that showed:
Other Help Commands
C-e Extending Emacs with external packages
p Search for Emacs packages (see also M-x list-packages)
P Describe a specific Emacs package
t Start the Emacs tutorial
M-x help-quick-or-quit Display the quick help buffer.
e Show recent messages (from echo area)
l Show last 300 input keystrokes (lossage)
. Show local help at point
I wonder if typing the suggested 'M-x help-quick-or-quit'
is really a quick way to get help?
Then I typed 'M-x help-quick-or-quit RET' but it doesn't exist
with "[No match]".
Then after 'C-h C-h' I tried to type 'q' (that means 'quick')
but it closed the Help window.
Finally, I opened the source code and found the command
'M-x cheat-sheet RET' that displayed the Help buffer.
But there is 'undo' displayed as bound to 'C-x u', not to other keys.
