16.2 Activation and Delimiter Gestures

Activation gestures terminate an input "sentence," such as a command or anything else being read by accept . When an activation gesture is entered by the user, CLIM will cease reading input and "execute" the input that has been entered.

Delimiter gestures terminate an input "word," such as a recursive call to accept .

*activation-gestures*

*standard-activation-gestures* 

Summary: The default set of activation gestures. The exact set of standard activation is unspecified; it includes the gesture corresponding to the #\Newline character.

with-activation-gestures [Macro]	

Arguments: (gestures &key override) &body body

Summary: Specifies a list of gestures that terminate input during the execution of body . body may have zero or more declarations as its first forms. gestures must be either a single gesture name or a form that evaluates to a list of gesture names.

If the boolean override is t , then gestures will override the current activation gestures. If it is nil (the default), then gestures will be added to the existing set of activation gestures. with-activation-gestures must bind *activation-gestures* to the new set of activation gestures.

See also the :activation-gestures and :additional-activation-gestures options to accept .
