I went back to try the help button again this evening, when I tried it this afternoon my computer didn't have its controls hooked up and was on a monitor of a different size so it was in micro type. I was in flight and I either did not realize that the link to key commands on the ingame window was a link or else I clicked it and it didn't do anything, quite possibly the former. The link however does not work in the browser that opens when you hit the B button in the window that opens when you press the Help button while in flight, I expected it to. You must press the link first, then open the browser from the new window with the key commands in it. If you close the ingame window that has the control set up(key commands) and die or whatever you cannot open it again untill you are in flight.
This is the best implementation of a command list that I, (in my admittedly limited experience,) have seen. It is almost perfect in my view. The problems that I see with it are that it is only available in flight, it should be available in any help window, (until you had some stuff memorized you would want to be able to access it really easily, maybe even outside of the help menu, right on the clipboard.) It should be a little more prominent and clear that the text in the first help window is a link, it looks kind of like a heading above the stuff below so it is a little confusing. Maybe it could explain that you can open it in a browser by pressing B, (the lag in the little identifier when you mouse over the B makes it easy to miss,) and that you can print it out. Frankly I think this as good as a print out and would be substantially better than a print out if the window could be opened at anytime or even minimized while retaining scroll position sort of like the text buffer. I would make it as easy to find as possible, but that is me. It really is remarkably good.
