Version 1.9
Go+ key
The Go+ key is used to do a go forward (with time) on any executor. First press Go+ then any key associated with the executor.
Don't mistake this key with the big Go+ key under the main executor faders - Read about it here.
As a default you already have the Go forward function on the 
key in the executors with a fader. The executors without faders will have the Toggle command on the key. You can change this functionality in the Change Functions of Executor Buttons window.
Advanced functionality
Pressing the 
key together with the Go+ key will give you access to the Unpark command. This can be used to unpark (or release) any parked element.
E.g. you need to unpark fixture number 1:
+ Go+ Fixture 1 Please
Fixtures or attributes can be parked using the Park command or the Pause key.
