One of the very powerful features of Marquee is the ability to very quickly record ideas to Looks (i.e., [REC] [BUMP]) that can later be called back by the command line, or referenced by cues as palettes or even played back on Look Masters as easily as pushing up a slider. Using multiple Look Masters in a live situation to layer pre-recorded ideas is called Busking.
Marquee's Fade Resolution allows you to continue writing to the stage with many many different playbacks and look masters and it keeps track of them all, allowing only the latest or highest to win. You can pile look upon look continually and then pull it all apart again, not just in reverse order, but in any order. Marquee will always maintain who is in control.
A good analogy is a stack of cards. Imagine the stage look is the top card you can see. If you have a jack, then you place on a queen, you're looking at a queen. Pull it off, you're looking at the jack. Put the queen back on, then a king on top of that. Now you're looking at the king. If you pull the queen out of the stack, you're still looking at the king. Pull off the king, you'll be looking at the jack. Just like that! No need to re-assert the jack.
With the flexibility of using multiple cue lists, look handles and bump buttons all used in combination with Priorities and Look Attribute Behaviors (described below), Marquee makes it trivial to operate effectively in any live situation.
After recording Looks to Look Master Pages, Marquee gives you many possibilities of how to bring that Look back up on stage. These are discussed fully in the topic called Looks under the section about the Look's properties, but it is worth showing the Look Properties' options here to exemplify two possible ways of using Looks in a live situation:

If, when recording a Look using moving lights, the intensities are included in the Record Options, the look will automatically receive the properties as shown above. That means that as you push up a Look Slider, all the moving light attributes will quickly set themselves into position and leave you with just the intensity level on the slider. Moving the handle in the opposite direction, as the slider reaches zero, all the attributes will be released and will return to whichever playback or other look was controlling them before this look was brought up.

If you want to have more control of how the fixtures will respond, change the properties of the Look (i.e., [VIEW] [BUMP]) and alter the Attribute Behaviors. This audience blinder look, which has very high priority, will manually control the intensities of the lights coming up (and possibly others going down if they are recorded at lower levels in this look). The Position will follow your movement with the handle whereas the color will go to its recorded state as soon as you move the handle and the recorded strobe value won't start until you reach the top.
If you record a Look using Linear Movement, and you set the Position behaviour to Manual, you can use the Look Handle to move fixtures in straight lines. (i.e., the light will move in a straight line from where ever it is on stage to the recorded position such that if you have multiple looks set up, you can move a group of lights to any position on stage, essentially using your moving lights as manual follow spots.)
Note:
If you are running a show live, it is handy to setup the A/B or C/D handles to control how long attributes get to their new level and how long they should take to return to their old levels once released. In combination with Busking, this makes Marquee a very flexible Live Concert desk.
