If you use Symbolics Genera (or the Common Lisp Interface Manager, see for example McCLIM), the GUI interactions will seen as 'gestures' and not as clicks. For example there could be a Select gesture. These gestures then invoke commands. The commands created by mouse gestures will be recorded in the interactor history like a command which has been typed to the interactor. Pointer gestures are : select, describe, delete, menu, edit,

Thus one gets a history of commands, which also can be reused, even from mouse gestures. Selecting a command from a menu or direct manipulation usually will lead to a recorded commnand in the interactor. The interactor runs a command loop.
