On FLX S48 consoles, there is not a dedicated Back button. However, you can configure the GO button, so that if you hold SHIFT and tap the GO button, you pause your cue transitions or go back to the previous cue. To do this, you can hold the SETUP key, and tap the Master Playback’s button. This will open the Playback Settings. The bottom row of options are the button functions. If you hold the Z/SHIFT key, you will see the current shifted option indicated. Keeping the Z/Shift key held, tap the “Pause” option, and then release the Z/Shift key. You can then press OK on the Playback Settings.

Now, if you are mid-way through a cue transition, SHIFT + GO will Pause the transition. Another press of SHIFT + GO, will Go back to the previous cue.
