To add different kinds of objects, navigate to the right hand side of the screen for the vertical menu bar. You can choose from different fonts, characters, props, shapes, images and videos.
Some objects are only available to users with a paid account, so avoid anything marked "PRO" or "PRO+".
To edit the objects on your slide, click on the item you would like to edit, and a pop up will appear with many options! You will have different options for editing depending on the item.
For example, when editing a character, you have the option to swap the character for a different one, animate the character, flip them, rotate them and more.
For a list of all the editing features visit the Working with Objects PowToon guide.
