Global Clipboard Patch (17370)

Text, ID names and RGB colours in the interface are now copied to and pasted from the system clipboard allowing them to be copied from and pasted into the text editor. Colours are encoded as floats in the form [r.rrrrrr, g.gggggg, b.bbbbbb] making them easy to use in Python scripts.
