I am trying to set up my computer (running Crunchbang Linux Waldorf and i3) so that it is always, by default, configured so that pressing Ctrl + Shift and arrow keys resizes the window according to the direction of the arrows.

The i3 user guide provides this example which I think is very close to what I want:

mode "resize" {
    # These bindings trigger as soon as you enter the resize mode

    # Pressing left will shrink the window’s width.
    # Pressing right will grow the window’s width.
    # Pressing up will shrink the window’s height.
    # Pressing down will grow the window’s height.
    bindsym j           resize shrink width 10 px or 10 ppt
    bindsym k           resize grow height 10 px or 10 ppt
    bindsym l           resize shrink height 10 px or 10 ppt
    bindsym semicolon   resize grow width 10 px or 10 ppt

    # same bindings, but for the arrow keys
    bindsym Left        resize shrink width 10 px or 10 ppt
    bindsym Down        resize grow height 10 px or 10 ppt
    bindsym Up          resize shrink height 10 px or 10 ppt
    bindsym Right       resize grow width 10 px or 10 ppt

    # back to normal: Enter or Escape
    bindsym Return mode "default"
    bindsym Escape mode "default"
}

# Enter resize mode
bindsym $mod+r mode "resize"

But I want to build it in natively, without having to enter and exit resize modes. I just want to use arrow keys, not j,k,l and semicolon keys.

Any thoughts on how I would do that?
