​Agreed.  It is natural for people to start programming things in Emacs
with a single frame and multiple windows.  As they expand their knowledge
to multiple frames and selecting a window in another frame, they'll want to
know the extent of what select-window handles and what it doesn't.  Their
could be simple explanations and references on input focus like:

Although this selects the window's frame, it does not alter the frame's
position in the window stack (see `raise-frame') nor does it direct input
focus to that frame.
To do both of those at once, see `select-frame-set-input-focus'.
