# Selection actions

This part of the ProBuilder toolbar provides access to selection modifiers and actions.

![Selection buttons on the ProBuilder toolbar](images/tool_selection.png)



Depending on whether you have the [Toolbar display mode](toolbar.md#buttonmode) set to **text** mode or **icon** mode, the selection action button displays the following to indicate what state the action is in:

* In **text** mode, the button displays the label text followed by a colon and the name of the state. For example, the [Select Hidden](Selection_SelectHidden.md) action displays either **Select Hidden: On** or **Select Hidden: Off**.
* In **icon** mode, the button displays a visual cue that reveals the action's current state. For example, the [Orientation](HandleAlign.md) action uses these three icons to indicate the handle alignment states: ![Orientation: Local](images/icons/HandleAlign_Local.png) (*Local*), ![Orientation: Global](images/icons/HandleAlign_World.png) (*Global*), and ![Orientation: Normal](images/icons/HandleAlign_Plane.png) (*Normal*).

The documentation for each action includes information about these visual indicators.

> **Note:** Some actions also have extra options or custom settings available. These action buttons have a special indicator in the top-right corner. The documentation for each action includes information about these options.
