Description

The class of commands. These are commands that can be grouped together in a command table to form the set of commands available to an application (available, for example, from the menu bar of the application). The resulting command object can then be executed by calling
execute-command.

The function: init-keyword is the command function that is called by the command object. A command function is rather like a callback to a <command> object: a command can be executed via execute-command, which then invokes the command function. Command functions take at least one argument: a <frame> object.

The arguments: init-keyword are the arguments passed to the command function.
