"Global" selection for magic wand

[drakbar]

In other paint programs, such as Paint.NET or Pinta there is a global mode for the magic wand (the paint bucket or fill too as well) that can be toggled on. When you select a pixel it will find matches in the entire canvas, and add that to the selected area.

A good demo for its uses case is as follows. Say that I have the following grid area.

Now I want to change the grid lines from black to some other color.
Currently, I would select each interior area in the whole canvas and invert (ctrl+i). Or I can select all and hold down ctrl and then select each interior area. Either way I have to go to each area and click inside it. I would then be left with only the lines in the selected area and now I can apply my color of choice.

A global toggle mode would allow me to select any pixel in these line segments, and all black pixels in the image would then be selected. This would work for other selection modes as well. So if I selected the entire canvas (ctrl + a) and then held down the ctrl key and clicked any pixel in the interior area all transparent pixels in the canvas would be deselected.

I feel like this could be an easy win with high impact.

Thanks!

There is already a select by color tool that does the same thing

Nice! I was about 50% certain that I was missing something.
