Help: How do I create rules for the M keys?

Created by: Hubro

I have enabled "Divert G-keys" and launched Solaar with -dd. When I press my M1, M2, M3 and MR keys, respectively, I see this output in the terminal:

There are 6 notifications in total, the first being the key-down for M1, the second being the key-up for M1, the third being key-down for M2 and so on.

So it seems like all the information is here, I just need to know how to write the rule.

Reading the docs, it seems like I need to write a "Test" condition for this, but unfortunately the documentation for that is brief and had no examples:

Test conditions consisting of a sequence of three or four integers use the first two to select bytes of the notification data. Writing this kind of test condition is not trivial. Three-element test conditions are true if the selected bytes bit-wise anded with its third element is non-zero. The value of these test conditions is the result of the and. Four-element test conditions are true if the selected bytes form a signed integer between the third and fourth elements. The value of these test condition is the signed value of the selected bytes if that is non-zero otherwise True.

After reading this, I barely have any more of a clue how to write this rule than I did before reading it. I need to write a sequence of 3 or 4 integers. Are they comma separated? Space separated? Are they formatted as decimal numbers? Binary numbers? No matter what I write in this box I get the error "Test string argument not name of a test". The first 2 numbers selects the bytes from the notification. How exactly? These docs are sorely missing a couple of examples to clarify these questions.

So I'm guessing I need to write an "And" rule like this:

  • And
    • Feature: MKEYS(8020)
    • Test: <first byte> <first byte> 01/02/04

But how do I write the test?
