Modification Keys + Mouse Movement, How do that?

[AugustoGodoi]

Hello everyone,

I need a help with my code.

I don't know the best practice to do CTRL + Mid Mouse Button + Mouse Movement Up

Below you can see my code:

(defcfg)

 

(defsrc
  PageUp
  PageDown
  NumLock kp/ kp* kp-
  kp7 kp8 kp9 kp+
  kp4 kp5 kp6
  kp1 kp2 kp3
  kp0 kp. kprt
)

 

(defalias
  ;; Isometric view shortcut in Creo
  ;; iso (multi lctrl d)
)

 

(deflayer main
  _
  (layer-switch mouse)
  NumLock kp/ kp* kp-
  kp7 kp8 kp9 kp+
  kp4 kp5 kp6
  kp1 kp2 kp3
  kp0 kp. kprt
)

 

(deflayer mouse
  (layer-switch main)
  _
  NumLock (multi lctrl mmid(movemouse-left 10 1)) (multi lctrl mmid(movemouse-right 10 1)) (multi lctrl mmid(movemouse-up 10 1))
  (multi mmid(movemouse-down 10 1)) (multi lshift mmid(movemouse-up 10 1)) (multi mmid(movemouse-up 10 1)) (multi lctrl mmid(movemouse-down 10 1))
  (multi lshift mmid(movemouse-left 10 1)) F7 (multi lshift mmid(movemouse-right 10 1))
  (multi mmid(movemouse-left 10 1)) (multi lshift mmid(movemouse-down 10 1)) (multi mmid(movemouse-right 10 1))
  C-d C-2 _
)

So when I release the button for example the kp4, the mouse movement continue indefinitely.

What I can fix this?
Or what the beat way to do this?

An update: the "lctrl" key is working well, but the "lshift" key continues moving after the button is released. It does not apply the Shift modification, only the movement.
