Hi


After thinking about learning elisp for years, today I've tried my first 
script. First I made some macros that worked as I intended, and then 
using this tutorial of Protesilaos I was able to transform those macros 
into elisp code.

(thanks a lot)


My situation: I am using Protesilaos' package logos, and I would like to 
add to it something (a hook?): to mark the position where my eyesight 
must go. Example:

My problems:

  * I don't know how to make my code work always and only when in
    logos-mode.
  * I get those jumps pressing 1, 2 and 3. I would like to use just 1
    key (for example SPACEBAR) not 3 keys to run the function.


My code:


(defun posicion1 ()
   (interactive)
   (next-line 1)
   (beginning-of-visual-line)
   (forward-char 6)
)


(defun posicion2 ()
   (interactive)
   (forward-char 23)
)


(defun posicion3 ()
   (interactive)
   (end-of-visual-line) ;;C-e
   (backward-char 7)
)

(define-key global-map (kbd "1") #'posicion1)
(define-key global-map (kbd "2") #'posicion2)
(define-key global-map (kbd "3") #'posicion3)


Additional problem: I don't know how to recover keys 1, 2 and 3 to their 
normal functioning, right now I can't type 1, 2 or 3 on my Emacs. xD


I think it could be interesting to use just SPC, instead of 1, 2 and 3. 
Maybe it could be done using conditionals, like in this not-working example:

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


(defun posicion1 ()
   (interactive)
   (next-line 1)
   (beginning-of-visual-line)
   (forward-char 6)
   (setq posicion 1)
)


(defun posicion2 ()
   (interactive)
   (forward-char 23)
   (setq posicion 2)
)


(defun posicion3 ()
   (interactive)
   (end-of-visual-line) ;;C-e
   (backward-char 7)
   (setq posicion 3)
)




(defun salto ()
   (interactive)
   (if posicion 1
     (posicion2))
   (if posicion 2
     (posicion3))
   (if posicion 3
     (posicion1))
)

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



Any help, advice, warning, or menace are welcome.

Best regards :-)
