other all programming languages used.
The Prefix is M-<space>. The ~which-key~ Package provides help on the keys.

Also, repeat-maps can help for movement and marking.

Depending on the mode, hideshow may be a good solution.
hs-minor-mode creates a menu.

Depending on the mode, hideshow may be a good solution:

Two functions are defined for cycling visibility: 

 #+begin_src emacs-lisp

#+begin_src emacs-lisp

* Outline

 Outline mode comes in handy,
 - when hideshow does not work properly
 - when you aim to shift whole code blocks
   

   (defun my/outline-overview ()
     "Show only outline headings."
     (outline-show-all)
     (outline-hide-body)))

         (setq ve/is-outline-overview nil)
         (defun ve/outline-overview ()
            "Show only outline headings."
            (interactive)
            (outline-show-all)
            (outline-hide-body)
            (setq ve/is-outline-overview t)
            )
      (defun ve/outline-reset ()
            "Show only outline headings."
            (interactive)
            (outline-show-all)
            (setq ve/is-outline-overview nil)
            )
         
         (defun ve/toggle-outline-overview ()   
           "toggle outline headings."
           (interactive)
           (if ve/is-outline-overview
      	    (ve/outline-reset)
               (ve/outline-overview)
             )
           )
