Can one use `occur' (M-s o) with case-fold-search disabled, somehow?

Can one use `occur' (M-s o) with case-fold-search disabled, somehow?

[Alan Mackenzie]

Hello, Emacs.

It seems that increasingly I want to do M-s o on a buffer for some
regexp such as "\\_<eq\\_>", looking for occurrences of "eq", but my
results are swamped by unwanted occurrences of "EQ".  This is not good.

I've looked at the Emacs manual (but not the Lisp code), and there
doesn't seem to be a way to get case sensitive matches.  Is this in fact
the case?

If so, this is also not good.  Why don't we use the key sequence M-s O
for this?  The command could be called `occur-with-case', or something
like that.

Comments?

You might want `M-x toggle-case-fold-search'，or you can proabably
define a keyboard macro if you want case sensitive search frequently.

Default bindings seem to avoid having shifted letter keys, does
anyone know why?  I don't remember reading about this in key
bindings section.  Using only two modifiers seems like a good
reason.  Vim also uses two modifiers constantly, but we don't
hear about a Vim pinkie.  Boo, talk about marketing...

Because it's easy to accidentally leave the Shift key pressed.

AND Because it's easy to accidentally left CapsLocks on.
