The edits of the cutting room. Every edit changes every script on the set at once; things on a timer never move. A scene grants only some of the tools, each a set number of times. One edit takes a run of beats: each tool's card says how long a run it takes.
CUTOne CUT removes a run of any length from every script.
In one line: nobody plays those beats.
The strip gets shorter: those beats are gone from every script at once. Everyone after them comes earlier, but things on a timer keep their beat, so a cut moves the cast against the timer.
A cut takes the same beats from every looping script, so it shifts each loop by a different amount: that is how you split two guards who walk in step.

REPEATOne REPEAT plays a run of up to 8 beats twice.
In one line: everyone plays them twice.
Choose one of her steps and repeat it, and she takes that step twice. Repeating a wait only plays the wait twice.
Everyone else on a script repeats those beats too, so a guard's loop grows by the same beats.

REVERSEOne REVERSE plays a run of 2 to 8 beats last to first.
In one line: everyone plays them last to first.
The beats play in the other order, but every move keeps its direction: a step right is still a step right, just at a different time.
Reverse fixes who else is there when she arrives: everyone's beats in that stretch swap order, not only hers.

FLIPOne FLIP turns steps around, open into shut, up to 8 beats.
In one line: left becomes right, up becomes down, open becomes shut.
Each beat in the stretch is turned round for every script, in the same order.

HOLDOne HOLD adds 1 to 4 waits before the run: one per beat.
In one line: everyone waits.
Pick 1 to 4 beats and press HOLD: that many waits go in front of them, one for each beat picked. Everyone on a script stops for those waits. Things on a timer keep going, and bolts already in the air keep flying, so a hold lets the timers catch up while the cast waits.

MOVEOne MOVE sets a run of up to 8 beats in another gap.
In one line: the same beats, played somewhere else in the take.
Pick the beats, press MOVE, then pick the gold line where they go. They leave every script at once and go back in at that line, for everyone, so the strip keeps its length.
Things on a timer keep their beat, so moving a pause to before a danger or after it changes what she meets when she gets there.
