I'll try to explain this.
This is what Emacs does for isearch/search.
If you go to the *scratch* buffer, and you do
C-s T C-s C-s
you only jump on 'T', that is, you skip the 't'. This is regardless
on the `case-fold-search' value.
Calling from Lisp:
(search-forward "T" nil t)
we'll also jump on the 't' if `case-fold-search' is non-nil.
I want the analog behavior for zap-to... commands: automatic
case sensitivity when the char is uppercase.
I want this behavior on interactive calls only, for instance when users
do `M-z'.
How to detect that the users are calling these commands interactively?
I got inspired from this comment found at the docstring of
`called-interactively-p' (Stefan wrote that):
"Instead of using this function, it is cleaner and more reliable to give your
function an extra optional argument whose ‘interactive’ spec specifies
non-nil unconditionally ("p" is a good way to do this), or via
(not (or executing-kbd-macro noninteractive))."
