+	The "keyboard palette widget" is a thing for visually representing hotkeys.
+
+	It lays out a bunch of clickable buttons similar to the ascii latter keys on a qwerty keyboard. Each one has an icon and a letter associated with it. If you hold shift, it can change to a second page of items.
+
+	The intention is that input would be layered through some redirects. Normally, ctrl+letters are shortcuts for menu items. Alt+letters are for menu opening. Logo+letters are reserved for the window manager. So this leaves unshifted and shifted keys for you to use.
+
+	My convention is that F-keys are shortcuts for either tabs or menu items.
+
+	Numbers are for switching other things like your brush.
+
+	Letters are thus your main interaction, and symbols can be secondary tool changes.
+		You could be in one of three modes:
+			1) Pick a tool, pick a color, and place with a thing (really mouse interaction mode)
+			2) Pick a tool, place colors directly on press (keyboard interaction?)
+			3) Pick a color, use a tool
+			4) vi style sentences
+
+	It will emit a selection changed event when the user changes the selection. (what about right click? want separate selections for different buttons?)
+	It will emit a rebind request event when the user tries to rebind it (typically a double click)
+
+	LETTERS (26 total plus shifts)
+	NUMBERS / NUMPAD (10 total plus shifts)
+	OTHER KEYS (11 total plus shifts)
+	`   - =
+	     [ ] \
+	    ; '
+	  , . /
+
+	Leaves: tab, space, enter, backspace and of course: arrows, the six pak insert etc. and the F-keys
+
+	Each thing has: Icon / Label / Hotkey / Code or Associated Object.
+
+	USAGE:
+
+		Create a container widget
+		Put the keyboard palette widget in the container
+		Put your other content in the container
+		Make the container get the actual keyboard focus, let this hook into its parent events.
+
+	TOOLS:
+		place, stamp, select (circle, rectangle, free-form, path)
+		flood fill
+		move selection.. move selected contents
+		scroll (click and drag on the map scrolls the view)
+
+	So really you'd first select tool then select subthing of tool.
+
+	1 = pen. letters = what thing you're placing
+	2 = select. letters = shape or operation of selection
+		r = rectangle
+		p = path
+		c = circle
+		e = ellipse
+		q = freeform
+		a = all
+		n = none
+		z = fuzzy (select similar things)
+		f = flood fill <convenience operator>, then letter to pick a color/tile. fill whole selection, fill zone inside selection
+		m = move
+
+		select wants add, replace, subtract, intersect.
+
+	2 = replace selection
+	3 = add to selection
+	4 = remove from selection
+	5 = intersect selection
+
+	save/recall selection
+	save/goto marked scroll place. it can be an icon of a minimap with a highlight: 3x pixel, black/white/black, pointing to it from each edge then a 7x7 px highlight of the thing
