Unofficial help file for commands, identifiers, on events, and other things.
You will need to download the .chm help file compiler:
MD5: 53899BE5DA83419D772D5B97E653DA7C
Install it.
Open the "mhelp.hhp" file and click File -> Compile (or click the icon left of the sunglasses).
You can click the sunglasses icon to view the "mhelp.chm" file.
The program is a bit primitive, I use a external editor for editing all the files. (Close out of everything if you edit any of the "mhelp" files.)
Windows has a security feature that prevents running non-installed (downloaded) .chm files. You will need to Unblock the file by Right clicking the .chm file, click Properties, Unblock, Ok.
