XML explanation/example requested

[Laynezilla]

Can the readme or wiki expand on how to write the XML files? I've run through the issues and have found snippets of XMLs but they don't fully list all the available commands. Even an sample XML with different examples would be really useful for simple minds like mine. Specifically, I could only figure out how to configure macro keys to output on a key down press but holding down the key did not repeat the input (like a typical key would). How can I configure a macro key to behave just like another key, with the system's repeat delay and repeat rate?

System information:
Kernel version: 5.9.16-1-MANJARO
OS Type: 64-bit
DE: KDE Plasma
Sidewinderd version: 0.4.3-1 from AUR

Also, really appreciate the work done on this software. Thanks so much!
