Hi Greg

I think "logos" doesn't have a map, is it possible?

Thanks, Tomas. It seems the "if" part works, now I use my elisp just 
with the spacebar :-)

(add-hook 'logos-focus-mode-hook #'(lambda ()

(defvar posicion
   "Position where is the cursor.")

   (defun focusPointStart ()
   (interactive)
   (next-line 1)
   (beginning-of-visual-line)
   (forward-char 6)
   (setq posicion 1)
)

(defun focusPointInter ()
   (interactive)
   (forward-char 23)
   (setq posicion 2)
)


(defun focusPointEnd ()
   (interactive)
   (end-of-visual-line) ;;C-e
   (backward-char 7)
   (setq posicion 3)
)

(defun focusJump ()
   (interactive)
   (if (equal posicion 1)
     (focusPointInter)
       (if (equal posicion 2)
       (focusPointEnd)
         (if  (equal posicion 3)
         (focusPointStart)))))

(define-key global-map (kbd "SPC") #'focusJump)
))

certainly possible (i don't use logos).

in fact,
----
https://gitlab.com/protesilaos/logos/-/blob/main/logos.el
----

has the lines

----
;; Logos does not define any key bindings.  Try something like this:
;;
;;     (let ((map global-map))
;;       (define-key map [remap narrow-to-region] #'logos-narrow-dwim)
;;       (define-key map [remap forward-page] #'logos-forward-page-dwim)
;;       (define-key map [remap backward-page] #'logos-backward-page-dwim))
;;
;; By default those key bindings are: C-x n n, C-x ], C-x [.
----

which certainly implies no map.  and, iiuc, *these* =define-key= lines
are global, i.e., remain true whether you are in, or out of, logos mode.

cheers, Greg

Hi,

maybe you want to cleanup a bit:

(defun focusJump (posicion)
  (interactive "nPosicion: ")
  (case posicion
    (1 (focusPointInter))
    (2 (focusPointEnd))
    (3 (focusPointStart))))

BTW: As lisp doesn't distinguish case, it is common practice in lisp
to seperate words in symbols with dashes like 'focus-jump,
'focus-pont-inter, 'focus-point-start, etc.

Just to avoid confusion: Emacs Lisp does distinguish case. Traditional
Lisp doesn't. I know you know, but people could misunderstand the above.

The rest stands: in Emacs Lisp it's customary to write variable and
function names with dashes, in good ol' Lisp tradition.

Yes, that was a bit imprecise ;-)
