Unlike older theatrical consoles that only have one cue list (i.e., one and only one Cue 1), Horizon can have an unlimited number of cue lists (Basic is limited to three). Each cue list has a number of options as seen below. HTP mean Highest Takes Precedence, LTP mean Last Takes Precedence and LTPK mean Last Takes Precedence Keep.  The LTPK cue lists are great for “base” looks that re-instate themselves once another cue list, that were previously overridden, are released.
