BUILT-IN MATHEMATICA SYMBOL

Trigger

Trigger[Dynamic[u]]
represents a trigger that can be pressed to make the dynamically updated value of u be continually increased with time from 0 to 1.

Trigger[Dynamic[u], {u_min, u_max}]
makes u vary from

to

when triggered.

Trigger[Dynamic[u], {u_min, u_max, du}]
makes u vary in steps du when triggered.

Trigger[Dynamic[u], {u_min, u_max}, ups]
makes the value of u increase at a rate of ups units per second when triggered.

MORE INFORMATION

In Manipulate, ControlType specifies that a particular variable should be controlled by a trigger.

The default duration after triggering for a variable to go through its range is 5 seconds.

Trigger[Dynamic[u], {u_min, Infinity}] runs forever after being triggered, with u increasing by 1 every second.

The following options can be given:

AnimationRate	Automatic	the rate at which variables vary
AnimationRepetitions	1	how many times to run before stopping
Appearance	Automatic	the overall appearance of the trigger object
AppearanceElements	Automatic	elements to include in the displayed trigger
Exclusions	{}	specific u values to exclude
DefaultDuration	5.	the default duration in seconds
DisplayAllSteps	False	whether to force all discrete steps to be displayed
Enabled	Automatic	whether the trigger is enabled, or grayed out
ImageMargins	0	margins around the image of the displayed trigger
ImageSize	Automatic	the overall image size of the displayed trigger

The following elements are included in a default trigger: , , . These elements can be specified in any order in a list given as the setting for AppearanceElements. Additional possible elements include all the appearance elements for Animator.
