Here's what you do - on the online editor, you just click on the Palette on the right shown here in the thumbnail (Palette.jpg) which will bring up the next screen - the copy / paste screen shown in the second thumbnail (Copy_Palette) thumbnail... on the bottom left you'll notice 2 icons - these are the copy and paste icons...
You got to fiddle around a bit in this editor so you can get the hang of it, but it isn't that difficult, and once you get the hang of it - it's relatively simple... Oh, by the way - you can toggle between the pallettes by clicking the big X icon and the palette Icon...
