Search for Function

To search command by name, Alt+x apropos-commandCtrl+h a】.

To search both function and command names, Alt+x apropos-command with a empty argument, like this: 【Ctrl+u Ctrl+h a】.

(In emacs, “commands” are a subset of “functions”. Commands are functions that can be called interactively (by typing 【Alt+x】).)

To search variable names, Alt+x apropos-variable.

To search variable values, Alt+x apropos-value.

To search all symbols space (commands, functions, variables, faces), Alt+x apropos.
