Conventions
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and explanations of their meanings.
Sequences of operations, for example, adding nodes to the Node Editor or objects to the 3D view, are written as follows:
Open the Blender User Preferences panel (Ctrl + Alt + U) and go to the System tab, which is the last tab to the right of the panel.
This means that you need to press the keys at the same time, then place the mouse arrow on the Texture item in a pop-up menu, and click on the item.
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "clicking on the Next button takes you to the next screen."
