How can I get the keyboard shortcut for a given emacs command?

Is there any function to do this? something like the inverse of开发者_运维问答 "describe-key"?

Try the command where-is, for example:

M-x where-is find-file

You can try C-h w (it's bound to the where-is command).

Type M-x describe-function or C-h f then type in the function name you want to know about. It will display the key bindings associated to it.

In Lugaru's Epsilon Emacs, it is "describe-command".
