E
The Animate (E) command traces through a program one step at a time, with a user-selectable pause between each step, beginning at the current instruction. In the Source mode, CodeView pauses after each line of source text. In the Mixed or Assembly-only mode, CodeView pauses after each instruction. The Animate command allows you to see how execution proceeds in your program.
You can set the time the command pauses with the Trace Speed (T) command or by choosing Trace Speed from the Options menu.
To begin animating, you can also choose Animate from the Run menu. There is no keyboard shortcut.
