Plays the night elf bell sound when it's your Battle Pet's turn, optimizing for accuracy while reducing tedium.

I came up with this grinding the 5,000 pet battle achievement. I noticed that an inordinate amount of time is spent watching and waiting for the exact moment the animation stops so I am able to click something. I usually started to resort to spam clicking. With repetition this mental activity is unnecessary, made me tired quicker, and gave me a headache over time.

I do pet battles from Razer Naga mouse keybinds using the Battle Pet Binds addon at http://www.curse.com/addons/wow/battle-pet-binds, and know pretty much the sequence beforehand, spelled out in number presses (such as 3 2 1 1 1 1) using the notes feature on the wonderful addon Rematch at http://www.curse.com/addons/wow/rematch.

This addon provides a subtle audio cue from when I need to select the next ability, enabling me to look at something else like a movie, only returning my eyes to switch pets. I can often do a whole encounter without looking at the screen.

This makes the grinding process a lot easier. Great for menagerie dailies! It also results in a lot less spam clicking, saving wear and tear both on your sanity and your mouse. It has even helped me stop screwing up a rotation because of overclicking or missing a swap.

The exact moment the bell rings is when the ability animation stops, so you will hear it midway between multi round abilities, and also at the end of the match. The channel is Master, so you can still hear it with sounds off. It even works bettter with all sound turned off... This channel and the actual audio file used may be edited in the lua.
