how to summon mounts(forgot)
Open up the collections interface. (It’s the horseshoe icon in the micromenu.) Click the mount tab at the bottom of the interface. You can drag mounts from the mount list to your action bars to use. (You can also directly mount from the interface itself by selecting a mount and the hitting the mount button in the lower left part of the interace, but that’s pretty cumbersome each time you want to mount.)
