I have an odd feature request but I think it could be useful. I have created some presets in my Devices-VST Connections window, and I was surprised that there is no assignable key command for being able to select quickly switch to a VST Connections Preset.
The reason I’m doing this is a bit hard to explain, but it has to do with using cue mixes and wanting to use the same pair of speakers to listen to various cue mixes. (Cubase does not allow you to assign your Stereo Out AND a Cue Mix to the same physical output simultaneously. So, this is why you have to switch via the F10 VST connections window)
