 For including an animation in a \pdf\ file, you can use the command |\movie|, which is explained below. Depending on the used options, this command will either setup the \pdf\ file such that the viewer application (like the Acrobat Reader) itself will try to play the movie or that an external program will be called. The latter approach, though much less flexible, must be taken if the viewer application is unable to display the movie itself.

@@ -193,7 +193,7 @@ This section explains how \beamer's color management works.
 
 In \beamer's philosophy, every element of a presentation can have a different color. Unfortunately, it turned out that simply assigning a single color to every element of a presentation is not such a good idea. First of all, we sometimes want colors of elements to change during a presentation, like the color of the item indicators when they become alerted or inside an example block. Second, some elements naturally have two colors, namely a foreground and a background, but not always. Third, sometimes elements somehow should not have any special color but should simply ``run along'' with the color of their surrounding. Finally, giving a special color to every element makes it very hard to globally change colors (like changing all the different kind-of-blue things into kind-of-red things) and it makes later extensions even harder.
 
-For all these reasons, the color of an element in \beamer\ is a structured object, which we call a \emph{\beamer-color}. Every \beamer-color has two parts: a foreground and a background. Either of these may be ``empty,'' which means that whatever foreground or background was active before should remain active when the color is used.
+For all these reasons, the color of an element in \beamer\ is a structured object, which we call a \emph{\textsl{\beamer}-color}. Every \beamer-color has two parts: a foreground and a background. Either of these may be ``empty,'' which means that whatever foreground or background was active before should remain active when the color is used.
 
 \beamer-colors can \emph{inherit} from other \beamer-colors and the default themes make extensive use of this feature. For example, there is a \beamer-color called |structure| and all sorts of elements inherit from this color. Thus, if someone changes |structure|, the color of all these elements automatically change accordingly. When a color inherits from another color, it can nevertheless still override only the foreground or the background.

 Depending on the current mode, you may wish to have certain text inserted only in that mode. For example, you might wish a certain frame or a certain table to be left out of your article version. In some situations, you can use the |\only| command for this purpose. However, the command |\mode|, which is described in the following, is much more powerful than |\only|.
 
 The command actually comes in three ``flavors,'' which only slightly differ in syntax. The first, and simplest, is the version that takes one argument. It behaves essentially the same way as |\only|.
