Thanks. It helps since misery loves company.

I'm not using frames. However, I tried view-file-other-frame and hit
`q'. I expected either the buffer or the frame to go away, but as you
said, it was iconified instead. Ew.

At best, I'd like `q' to kill the *Help* buffer or buffer in
view-mode. At worst, I'd like to bury it. But for me, `q' either does
nothing (maybe after visiting the *Help* buffer), or closes the window
but leaves the *Help* buffer in the #2 spot so a subsequent C-x b
takes me not to the mh-e.texi file that I was expecting but to *Help*.

I find that the use of `C' reliably does what I want (as well as C-x
k, of course). However, my fingers really prefer `q'. I think it's a
bug that I can't bind `q' to View-kill-and-leave.

I agree with you that all those ways of quitting view-mode are silly.
Once you're in view-mode, how you got there is immaterial. I want `q'
to do the same thing whether I ran view-mode manually, whether I'm in
a *Help* buffer, whether I ran `v' from dired, or have view-read-only
turned on. KISS. Perhaps you and I need to come up with recipes that
reliably show what we mean, but I would argue that if the exit path
were more simple, we wouldn't be here in the first place. Rather than
try to find and isolate a small bug, we should redesign and simplify
the exit path.

For example, I think view-mode should take the same design as
customize, in which there is a single function to exit
(Custom-buffer-done), bound to `q', which buries the buffer, unless
the option custom-buffer-done-kill is turned on, in which case the
buffer is killed.

However, I would agree that now is not the time to do this.

My 2c anyway.
