Thanks for the speedy reply. I am using the bforartists keymap. The S of scale in the menu item is underlined so I thought that was the intended shortcut. The S key certainly behaves as a scale key. If, for example, I want to put a number of selected faces at the same level on the X axis, I would press S, X, 0 to do it. If you press R (or use the icon on the left) the scale function doesn’t do this. In the main Blender branch, pressing S does both of these things from the same shortcut.
