Normally incremental search can be repeated by pressing C-s multiple
times.
Why if I remap incremental search to C-f I CANNOT repeat it by
pressing C-f multiple times?....
Here is how I remapped it...
(global-set-key "\^f" 'isearch-forward)

C-s runs the command isearch-forward
which is an interactive compiled Lisp function in `isearch.el'.
Do incremental search forward.
With a prefix argument, do an incremental regular expression search instead.
As you type characters, they add to the search string and are found.
The following non-printing keys are bound in `isearch-mode-map'.
"""
And isearch-mode-map contains this:
(19 . isearch-repeat-forward)
(19 is C-s.) So you need to rebind that too.

other mentioned you need to bind isearch-repeart-forward too, but that
won't work if you just bind them to global map, because when you run
isearch, you are technically in isearch mino mode.
Here's what to do. for example, if you want M-s to be isearch, then
do:
(global-set-key (kbd "M-s") 'isearch-forward)
(global-set-key (kbd "M-S") 'isearch-backward)
(add-hook 'isearch-mode-hook
(lambda ()
(define-key isearch-mode-map (kbd "M-s") 'isearch-repeat-forward)
(define-key isearch-mode-map (kbd "M-S") 'isearch-repeat-backward)
(define-key isearch-mode-map (kbd "M-n") 'forward-char) ; was isearch-
ring-advance
(define-key isearch-mode-map (kbd "M-p") 'kill-word) ; was isearch-
ring-retreat
(define-key isearch-mode-map (kbd "M-c") 'previous-line) ; was
isearch-toggle-case-fold
(define-key isearch-mode-map (kbd "M-r") 'forward-word) ; was isearch-
toggle-regexp
(define-key isearch-mode-map (kbd "M-e") 'delete-backward-char) ; was
isearch-edit-string
(define-key isearch-mode-map (kbd "<f11>") 'isearch-ring-retreat)
(define-key isearch-mode-map (kbd "<f12>") 'isearch-ring-advance)
)
)

• How To Reclaim Keybindings In Emacs
http://xahlee.org/emacs/ergonomic_emacs_keybinding_minibuffer.html
-----------------
PS when you look into isearch's map, you'll notice that it defines
quite a lot other features/shortcuts. I'd say, 90% of them are never
used once for those who have 4 years of emacs experience . For veteran
emacs diehards, say those who used emacs over 10 years, if i can make
a guess with my 10 years of daily emacs use and observation of other
emacs users, i'd say 50% of the shortcuts provided by isearch are
never used once in their life. These complexity and buried features
should be reorganized. The proper isearch key should be Ctrl+f or Ctrl
+g. That's the universal modern UI standard.

Yes, but why would anybody want M-s to be isearch?

If you put that functionality in isearch-mode-hook, you'll rebind these
keys EVERY time you start an isearch. I suppose, with the power of
modern PCs, you won't notice too much, but the cells in the isearch key
map might get a little worn out. :-)

I think you're very wrong there. Different users will use different
subsets of them, but do feel free to try to identify those which are
never used. I think you'd be surprised.

Emacs UI is good rather than modern. The term "find" is less accurate
than "search", because often the editor fails to find what you're looking
for. But it always searches. C-s is thus more mnemonic.

isearch is one of the most frequently used command (roughly within top
15). See:
• Emacs's Command Frequency
http://xahlee.org/emacs/command-frequency.html
under my ergonomic keybinding map, frequently used keys are on home
row. So, isearch is on homerow, and it happens to be on key for the
right pinky. On dvorak, that's s. I pulled the code example from my
map, so that's how it's is s.

Thanks. I haven't thought of that. I'll have to make it minor mode
soon.

Alan, do you have accumalated more keystroke for the stat?
the best way to objectively find out what commands are actually most
frequently used, is thru the stat program.
If you could, please tell your friends, and other developers on the
emacs list to try the command frequency.el.
http://xahlee.org/emacs/command-frequency.el
when we have a the stat from lots people, then a good look on emacs
keybinding can be had.

I think that's overkill, and that Alan was hinting that you could just
move those define-key forms to the top level. (Since isearch is dumped
into the emacs executable, isearch-mode-map is defined at startup.) Or
you could be extra-safe and use eval-after-load.
