Search for Function

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

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

To search variable names, call apropos-variable.

To search variable values, call apropos-value.

To search all symbols space (commands, functions, variables, faces), call apropos.
