Labels for a multi-(multi-function)-button wall switch

I bought a ZWave wall switch that looks like this :

Classy eh? EDIT thanks to @Darryl it has 4 independant buttons!

This wall switch responds to 4 actions for each of its buttons :

I therefore have 12 functions available (3 press modes and 4 buttons) for this wall switch. ZWave connection is not a problem.

I'd like to provide a way to show my non techie users which button does what when pressed somehow...

I'd use a model from what I have on my home's boiler but adding 12 functions grouped by type will take some place and be messy:

(French column names on the left post-it : "still","blinking")

I am already aware that grouping functionalites is necessary for user remembering, for example

Also, I think I should "keep" button configuration for myself and not tell my users, such as double press.

Here are some actions I am thinking for this particular wall switch:

Is there a good/easy/simple way to label these buttons and their type of press matching with functionalities?

My users (wife and children) are non techie but they can read and are not colorblind (I am, but its okay since I design the system)
I can do anything in my house, and this wall switch will just be glued on the wall
I suppose pictograms will not need further description (for example music notes for "turn on the hifi system" is enough)

Thank you for your help!
