Clarity of defintions of lighting terms..

Hi, I am doing an assignment on a LSC Maxim lighting desk, and finding the terms it uses in the op manual are different from what i am used to. If anyone could help clarifying the following terms it would be really helpful... 1. is a 'cue' the same as a 'scene'? If not what is the difference? 2. What exactly is a 'stack', is it different to a 'cue list'? 3. What is a 'cue list'..? 4. What are 'steps' in terms of a stack? 4. Also double check on the meaning of 'chase'? 5. Are a scene, cue , snapshot and step all really the same thing? These may seem like some obvious questions, but i have just been totally confused about them in the context of the manual compared to our assignment sheet. Any help would be great. Thanks
