change modifier to drag and drop windows

[yherve]

Hi.
By default, you can drag and drop windows using the 'mod' modifier. This is very convenient... except for left-handed people
because the left hand is on the mouse and the super key is on the left side of the keyboard.

On french keyboard there is this 'mod5' (alt-gr) modifier on the right side of the keyboard.

So I would like to be able to move windows with the mouse by pressing this 'mod5'. Is it possible ?
(Note that I don't want to global change 'mod' to 'mod5')

I don't think DND is possible. But something like this?

    Mod5+WheelScrollDown cooldown-ms=150 { move-column-right;}
    Mod5+WheelScrollUp cooldown-ms=150 { move-column-left; }
