I forgot to mention a key (pun intended) command that MCE Controller supports in the 1.0.3 documentation. The “key:” command allows you to simulate any alphanumeric keyboard key press. For example “key:3” is the same thing as pressing the 3 key on the keyboard. This command is implemented internally in MCE Controller rather than via the MCEControl.commands configuration file; which is why I forgot to document it.
I will update the readme file next time I release a version of MCE Controller.
