Help with my first elisp

[Ypo]

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 :-)
