ReadyGo Web Course Builder supports six levels of indentation on bullet pages.
Just to the left of the text dialog where you input content, you will see four arrows.
The up and down arrows allow you to move the content before the previous bullet or after the subsequent one.
The right and left arrows increase or decrease the level of indentation for the current bullet.
There is a number below these arrows that tells you the current indentation level for that bullet. You can change the graphics used for each bullet point by specifying graphic images in Appearance > Colors and Graphics (Bullet Pages tab).
