 This simply negates a variable, effectively turning it into its reciprocal value: if the variable 'Timecode.Enabled' is true it will be set to false, and vice versa.
+There are also some other syntax versions:
+<code xml>
+<step>
+  {
+    if(Math.IsNotEqual(Playbacks.Editor.Times.ChaseSpeed, 0.0)) {
+      ** Do Something **
+    } else {
+      ActionScript.SetProperty.Float("Playbacks.Editor.Times.ChaseSpeed", 1.0);
+    }
+  }
+</step>
+</code>
+and as of version 10, it is possible to write conditions in a more modern way:
+<code xml>
+<step>
+  {
+    if(Playbacks.Editor.Times.ChaseSpeed == 0.0) {
+       ActionScript.SetProperty.Float("Playbacks.Editor.Times.ChaseSpeed", 1.0);
+    }
+  }
+</step>
+</code>
+**It appears that the else hive must not be empty. If it is empty then Titan doesn't start, and the Log Viewer complains "Compliation of action script failed:... Unexpected token '' found." ** (The typo is courtesy of the Log Viewer :-) )
+If you only need the if hive, then omit the else altogether.
