FluidNC commands and setting use a $ format.

Commands are used for actions (like homing or disabling motors) or retrieve information (like gcode offsets). You can get a complete list of them with the $CMD command. Many commands have a full name format as well as a shorter version. Like $Gcode/Mode and $G.

Settings are used to set saved values. Most settings are now in the YAML file, but there a a few like $Confg/Filename that need to be outside the YAML file. You can see all of them with $S

Note: Details for each command will be added soon.
