What bindings start with H-z?

Question

When I type H-z, emacs waits for more input, so I assume something is bound to H-z plus something else, only in this case C-h k H-z also just waits for more input. How can I find out what is bound to what starting with H-z?

Answer 1

Emacs has a special case for this, hitting the help character (default: either C-h or F1) after an incomplete key sequence will execute describe-prefix-bindings and show you possible commands starting with it.

Answer 2

You can find the bindings that start with a prefix by pressing C-h or <F1> after the prefix. In your case, pressing H-z C-hwill list all bindings that start with H-z.
