Update documentation to (also) reflect button names on newer Launchpad models

[probonopd]

The Launchpad X has the following buttons (the square ones). I am putting them next to the buttons mentioned in the documentation, which I guess are the buttons from older models (the round ones).

At this point, I am just speculating (but am not really sure) that there is a 1:1 relationship between the old and the new keys.

It would be nice if the documentation would reflect both old and new buttons, since for users of Launchpad X the documentation is constantly referring to non-existing keys.

as mentioned in a previous ticket, this fixes your problem, but create problem for other users that have different launchpads. just use the button position instead.

Can you confirm that there should be a 1:1 relationship between the buttons I posted? So for example, "Note" = "user 1 Inst."?

(Maybe the question sounds a bit silly, but I have a hard time to figure this out for sure, as the behavior doesn't seem to match the documentation, as per my other ticket.)

what matter is the position of the button, just ignore the labels.
