When making Flash demos, activations and mouse clicks can be recorded by inserting a line act_sounds=SUR_ACT,SUR_ML,SUR_MR in the SURVO.APU file. The default WAV files listed above are in the directory <Survo>\U\SND. After making this modification and restarting Survo, the sounds are activated by keystrokes F2 L E and deactivated by F2 L e. When the sounds are activated, the first sound will heard when a command is activated by ESC or a double-click. The second sound relates to the mouse click by the leftmost button. The third sound relates to the mouse click by the rightmost button.
