Steve - obviously there are a few books and tutorials to skim through, but worth mentioning the meta-enter key (eg Cmd-enter on Mac) - this is spotter which is a universal grep and browser to help find things, as well as users of things (and lots more tricks)

Also, in the playground is where you can evaluate code like a repl- if you use meta-g on an expression you get a results inspector on the rhs which lets you explore and keep sliding over panes as you dive in (great for looking at results). You can also teach your own objects to add useful tabs to that browser to get a cheap ui (useful for starting out)

Thank you Sven and C��drick for the pointers.  An existing implementation of MQTT Client is a huge help and of course very useful for my learning.

I didn't know the Filter field could "or" so that is great to make things disappear.

Thanks for taking the time to show me how to load the code with Metacello.
