I would like to be able to select dimensions in drawings and lines that I've created in the drawing and press "R" to turn them red. I need to do this often enough to highlight disrepensies that a keyboard shortcut would save a lot of time in the long run. Does anyone know if this is possible and, if so, how to go about setting it up? As far as I can tell, the only color related keyboard shortcut that is possible is one that turns the line formatting toolbar on/off. Any input is appreciated, Thanks!
