In the thread "Finally, some documentation," it mentions that you can press F1 in the ZScript Editor to display the commands. I can't find a ZScript Editor; the closest I can get is the compiler. Also, where can you find the place where ZScripts are assigned a number which is selected for each item, FFC, etc.? Is that in the ZScript Editor?
ZScript Editor
The Editor is the compiler. Once you compile a script, a window will pop up asking you to assign the scripts to number slots.
As for F1, because of a slight repository misconfiguration the help file may not have been included in the last few builds. The next beta should contain the documentation inside ZQ.
