Action is the action object that is associated with the control. Actions allow an application to centralize the response to user commands. When a control is associated with an action, the action determines the appropriate properties and events of the control (such as whether the control is enabled or how it responds to an OnClick event).
To create actions at design time, place an action list component on a form or data module. Double-click the action list to bring up the action list editor. Add actions in the editor using its context menu. Once the actions have been added using the Action List editor, they appear in the drop-down list for the Action property in the Object Inspector.</p>

<p>Notes:
Controls that display text use either the Caption property or the Text property to specify the text value. The property that is used depends on the type of control. In general, Caption is used for text that appears as a window title or label, while Text is used for text that appears as the content of a control.
For some controls, such as TButton, it is not possible to change the color of the Caption. If you want to change the color of a button caption, you should use an alternate button type such as TSpeedButton or TBitBtn instead of TButton. With either TSpeedButton or TBitBtn, you can change the color of the Caption property by using the Font property.
For TLinkLabel, an HTML tag is declared inside the Caption property either at run time or at design time.</p>
