CmdPeriod allows you to register objects to perform an action when the user presses Cmd-. These objects must implement a method called -cmdPeriod which performs the necessary tasks. (You can add such a method in your custom classes.) Note that since Function implements -cmdPeriod as a synonym for -value, it is possible to register any function (and thus any arbitrary code) for evaluation when Cmd-. is pressed.
Registers an object to be cleared when Cmd-. is pressed. This object will stay registered until it is explicitly removed, and will thus respond to additional presses of Cmd-.
Removes an object that was previously registered.
Removes all objects that have been registered.
Registers an object to be evaluated once, and then unregistered.
Get or set the list of objects that are called when CmdPeriod is evaluated.
The number of times CmdPeriod has been called since startup.
