More commands in the selected style indicator (right-click menu):
** "White", "Black": Sets the fill or stroke to the corresponding color. (This may be removed when we have a color palette in the main interface, but for now these are very useful.)
** "Copy color", "Paste color": Copies or pastes the fill or stroke color (when it's color) to/from the system clipboard, as text in the #rrggbb format.
** "Swap fill and stroke": Exchanges fill and stroke (both their types and colors, if any).
Also:
* By popular demand, in Pen tool, if a new path is being drawn but not yet finished, Ctrl+Z cancels that unfinished path (i.e. does the same as Esc), instead of undoing the previous action.
* In Node tool, the ! key inverts node selection in the current subpath(s) (i.e. subpaths with at least one selected node); Alt+! inverts in the entire path. (This is similar to how these keys work in Selector, with current subpath(s) instead of the current layer.)
