I probably am missing something here, but:
I go to http://docs.particle.io/photon/firmware/ to check how a command works, (such as ANALOGWRITE()) which is really not writen in all caps, but in documentation it is ???
But to find the command, I do not see a short list of options, nor a search for command option. So, I have to scroll down the page (a long web page) looking for what I want. Is there a easier way to get to a command description?
The sample code section to the right does show most common usage and for quick finding you could use the nav-bar to the left and the “Search Page” feature of your browser 
How is this?
http://docs.particle.io/photon/firmware/#i-o-analogwrite
So, with the Arduino heritage, you may also find it useful to refer to their docs from time to time…
Two good solutions. Thanks a lot guys.
