A quick QB64 program to grab a brief command list and minor description from the web:
Run this and it generates a file called "Keywords.txt" on your drive which looks like the following:
It should probably be parsed a little better and cleaned up more, but it gives a quick working list of keywords and a minimal description of what they do for us, for quick reference.
