Hi, I have a question regarding click healing in isboxer with click bars.

I am leveling a new shaman and I have my ungrouped 85 priest following and healing her when needed. I plan to add and group with a DK when my shaman gets around lvl 58. I want to have my un-grouped priest follow the master and heal BOTH shaman and DK. I could just make and bind a few keymaps to a few keys, but I do not want to be overloaded with healing keys.

Is there a way that I can use the click bars for the healing without adding addons and with my priest un-grouped? thanks
