Ah, well Windows and Office Help have been about as useful as a rubber ice pick for as long as I can remember. Most versions ( though I haven't looked at one for a decade or so) would list the most obvious stuff- saying what Print does, for example - but have no entry explaining the function of several commands in the menus that weren't obvious, or that would be greyed out/non-functioning until some other mysterious condition was met.
And that is also very similar with flat pack instructions too. The easy stuff is clearly illustrated. but the bit that is particularly difficult to fit together will have no guidance in the written instructions ( if there are any) and will be illustrated as an oblique angle that totally fails to show how the two sections that you can't get to fit together are meant to. Especially if it's one of the chicken and egg sections (you can't get d and e to fit until you've put b and c together, but once you've b and c together there's no room for d and e...).
In both incidences I've always assumed that the writers have said "Sod it it's too difficult to explain, we'll leave that bit out"
