I've found highly useful information on the forum on how to toggle preference settings using Vscripts, for example using something like:
SetPref(33, NOT GetPref(33));
However, I'd like to make two scripts that, in one operation each, set the screen background, line thickness zoom, and black & white only preferences to predetermined values, regardless of what they were previously. Basically I'd like to switch betweeen my normal mode of working (no line thickness, black background, with colors visible), to a 'preview-like' mode, where I can see line thicknesses, the background is white, and all of the printed stuff is black. Any help? Thanks!
