Doom-emacs: [HOWTO] multiedit outside of the selection

[haditim]

Thanks a lot for this amazing project. I have some questions/suggestions to improve multiedit functionality:
I would like to have multi-cursor edit using a keybind + mouse button. Also would like to be able to navigate outside of the selected region once occurrences are marked.

• What are you trying to achieve?
  Something like this in VScode for the first request:
  
  And freedom in movement when occurrences are selected using evil-multiedit or multiple-cursor.el.
• What have you tried?
  I tried evil-multiedit-toggle-marker-here which just allows to add text at the selected points. Also tried binding:

(global-set-key (kbd "C->") 'mc/mark-next-like-this)
(global-set-key (kbd "C-<") 'mc/mark-previous-like-this)
(global-set-key (kbd "C-c C-<") 'mc/mark-all-like-this)

(global-set-key (kbd "C-S-c C-S-c") 'mc/edit-lines)

(global-set-key (kbd "C-S-<mouse-1>") 'mc/add-cursor-on-click)

which works okayish but does not support evil navigation keys and is a bit buggy in terms of going back and forward by words, etc. And if I used M-d for evil-multiedit, I would be limited to the selected area for changes. But sometimes it is necessary to start with a similar word and then edit further in the line. - Do you have screenshots/casts of this workflow in another editor or Emacs distro? (If possible, include names of specific commands or functions from other editors/kemacs distros) See above - Do you have extra material or links to resources that could help clarify what you are trying to do? https://kencenerelli.wordpress.com/2018/03/25/visual-studio-code-multi-line-and-multi-cursor-editing/ **System information**

While we _might_ be able to strong-arm evil-multiedit into doing this, this is more evil-mc's jurisdiction. I would also suggest you use that instead of multiple-cursors which, as you know, lacks evil support. On the other hand, I am not familiar with getting it to work with the mouse, as I do not use the mouse.

With the default keybinds, you can place a cursor down by pressing gzz. They'll be dormant until you press gzt to toggle them or until you switch to insert mode.

To get the mouse workflow working, perhaps something like this would work:

(defun make-cursor-here-then-move (event)
  (interactive "e")
  (save-excursion
    (let (mouse-drag-and-drop-region)
      (mouse-drag-region event))
    (evil-mc-make-cursor-here)))

(map! :i "<mouse-1>" #'make-cursor-here-then-move)

I've tried it with "<C-mouse-1>" but it didn't work very well. I'll look into it more next weekend.

Thanks a lot for the reply. Seems that evil-mc is exactly what I needed. I don't know why I hadn't recognized its existence in Doom.
Also the code for mouse click seems to be working although it starts to select the text at the same time, loses the first cursor and catches the last mouse position into the cursors (w/o a click). I wished evil-mc had a function similar to mc/add-cursor-on-click.
Thanks again for the amazing project and thanks for taking time on this.
