Also, in some cases it might be good to map two dimensions of the color space at a time, not just one.
It could be done, I suppose. But, unless you would limit that to 45 degree diagonals (equal changes in two dimensions), which is not that useful, I think we are miscommunicating. I'm thinking that horizontal arrows could alter one dimension in color space, while vertical arrows could alter another dimension. Since it doesn't have to be limited to arrows, another pair of keys could move in the third dimension of color space. To change more than one color component at the same time, it's better to have an interface that shows a color space, such as in the Word dialog box. That sounds plausible. I wonder if that could be programmed in Emacs Lisp. Also, some toolkits may have a widget for doing this job, and maybe Emacs could invoke it somehow. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
