More info on the UI and Macros forums for the shammy stuff:
The totem bar is mapped to action button IDs 133 to 144, and is split into three "pages":
* page 1 is cast by call of fire (133, 134, 135, 136)
* page 2 is cast by call of water (137, 138, 139, 140)
* page 3 is cast by call of air (141, 142, 143, 144)
Buttons 133, 137, and 141 are limited to fire totems
Buttons 134, 138, and 142 are limited to earth totems
Buttons 135, 139, and 143 are limited to water totems
Buttons 136, 140, and 144 are limited to air totems.
The base layout of the bar is:
call of {fire|water|air}, fire totem slot, earth totem slot, water totem slot, air totem slot, call of earth
