But how will the Sonder keyboard help you to remember hotkeys? Maybe I'm missing something. I can understand how it can show me that option-shift-2 is the Euro symbol but how can it show me that command-G is "Paste Only MIDI Notes"?

I don't even see how it will show you that option-shift-2 is the Euro symbol. You'd have to already be holding down option-shift for it to show up, wouldn't you?

So you'd have to already know most of the shortcut.

This product seems like a solution in search of a problem.
