## Shortcuts

A shortcut is not displayed

To display a shortcut in the interface, set the shortcut to the same action that is performed when the button is clicked.

Assign an action to the component if you haven't yet:

You can see the full list of actions in List of actions.

Keep in mind the following:

• The data types for actions must be the same. For example, in the following case the shortcut works but is not displayed: clicking on the button saves the “true” string to the results, and the Boolean value true is defined for the shortcut.
• If multiple actions are triggered when the button is clicked (action.bulk), the sequence of these actions for the shortcut must be the same.
• If you use a conditional operator to select an action, such as helper.if, the same conditional operator (helper.if) must be called under the same rules when the shortcut key is pressed.
