Content of the library you select in the Application toolbar is displayed in the Libraries toolbar.
The Libraries toolbar lets you scroll actions, materials, or models sorted in categories whose names appear on blue tabs.
By default, at the launch of the program, the Libraries toolbar is positioned below the Application toolbar and displays the modeling tools available.
If you click the border, you can drag it and obtain a floating panel.
To select the library to be displayed, just click the related icon in the Application toolbar or choose the Managers menu and select Modeling toolbar, Materials toolbar, or Models toolbar.
To scroll the content of the toolbar, just click a blue tab (Transform, Curves, etc.) and drag while holding the left mouse button down.
Scrolling can be also performed by clicking and dragging any point of the toolbar while holding the RIGHT mouse button down (Apple key + mouse button on the Mac). This way, you can scroll when no blue tabs are displayed.
When you double click a blue tab, all tools within a category are displayed/hidden.
If an icon contains two small blue arrows on the bottom right corner, you can click and hold to display a pull-out that contains other tools. You can then drag the cursor to choose the tool you want to use. When you are over each icon, the program displays the tool name.
