Introduction to the different selection modes proposed by Acrobat
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Page controls toolbar proposes a tool to select text and images:

   .. image:: /_static/images/select.png
      :align: center

This selection tool is not suitable to select some other standard PDF objects that are present in 3D PDF documents like:

   - « rich media » objects: 3D annotation, videos…
   - forms objects: Text fields, buttons…

This other selection tool is as default only accessible in the Forms and in Rich media plugin.
We recommend to add this selection tools to the “Quick Tools” toolbar.
To customize the Quick Tools toolbar, do the following:

   - Make a right-click in the top tool bars area
   - Select the Customize Quick Tools menu

      .. image:: /_static/images/customize-toolbar.png
         :align: center
   
   - In the plugins list, scroll down to the “Rich Media” plugin and open it

      .. image:: /_static/images/rich-media.png
         :align: center

   - Click on the “Select Object” icon at the bottom of the list
   - Then click on the right arrow to add this tool to the “Quick tools” toolbar
   - Click on Save

.. note::

   It is possible to remove the other default tools from the quick tools toolbar.

After this operation, the top toolbar should look like this:

   .. image:: /_static/images/new-toolbar.png
      :align: center

.. note::

   Note that the “Select Object” tool has the same icon that the standard selection tool.
   However, these tools are not behaving the same.
   The new one which has been added enables to select 3D annotation, text fields, buttons… in order to edit them (position, size, parameters…)

Usage of Grid and rulers - OPTIONAL
===================================

The display of the grid, rulers and guides may help when designing the PDF document
Grid:

- Activation : CTRL + U

View > Rulers & Grid > Show/Hide > Grid
Snap to Grid:

View > Rulers & Grid > Show/Hide > Grid
(no shortcut)
Rulers :

- Activation : CTRL + R

View > Rulers & Grid > Show/Hide > Rulers
Guides:

View > Rulers & Grid > Show/Hide > Guides

Explanation
-----------

The grid and rulers help positioning items such as buttons.
Grid and rulers can be displayed using short-cuts.

However, the Snap to grid option is accessible only through a menu.

Displaying guides is an alternative to the Snap to grid mode.
The guides can be defined by clicking inside a ruler, and by dragging the guide in the 3D annotation.
Guide are only a visual support, and they can easily be moved, deleted…
