How to summon mount
 

I've been away from WoW for two years and finally felt the call to reactivate my account.
I reinstalled a clean Realui with no other addons.
For the life of me I can't find or remenber where/how to summon a mount.
I know I've got dozens of them somewhere but all my random keypressing and googling has failed to produce a result.
I can't see a pet tab on the character screen nor anywhere else.
I'm not sure whether it's the UI hiding it or just my stupid brain forgetting the WoW keys.

Any help appreciated.

With the Warlored of Draenor came a feature: A "chest" for Mounts. If yor press the Menu button (button in the left corner) and press Mounts and Pets you should find your Pets, Toys and Mounts (and with 6.1 the Heirlooms too)
