VEX IQ Blockly command guide/definitions

Is there a command list for Robot Mesh Blockly for VEX IQ with definitions that describe what the command does? I have the basic idea about the commands, but the specifics I would like to be able to look up instead of learn by trial and error. The commands have a grayed out “Help” option when I right-click on them. Maybe this will show how the command is used at some time?

If you’re not looking at the IQ Blockly B Beta, this could be of use:

Thank you. I’ll read it.
