Description:
discover key bindings and their meaning for the current Emacs major mode
Discover key bindings and descriptions for commands defined by a buffer's major and minor modes. The command is inspired by discover.el and also uses the makey library. The output is pretty bare bones and not optimized but it seems to work already quite well for most modes.
