Pressing <<< followed by a key associated with an executor will take you one cue back in 0 seconds.
A <<< Please will do it on the main cue list.
Advanced Functionality
Pressing the 
key and then pressing the <<< key will give you the Black command. This is used to temporary blackout an executor. It'll put the dimmers to 0 but keep the other attributes active as long as you keep the executor key pressed. If the dimmers get's values from other executors, then they might still output dimmer values. When you release the key, then the dimmer values return.
E.g. you want to temporary turn down the dimmer values of executor 3 to 0%.
Press the +<<< keys, now press and hold one of the keys associated with executor number 3. The output will now be 0% as long as you keep the executor key pressed.
