+// Arrows in a layer in the home position.
+// Fn+Arrows = PgUp PgDn Home End, which is intuitive for me
+// 
+// Since QWERTY and WORKMAN keep angle brackets together, I wanted to place
+// other enclosing symbols on the same keys. So, 9 and 0 and [ and ] land there
+// in other layers. That informed the numbers placement, which informed the
+// function-key placement.
+//
+// To do:
+// - Improve LED indications (may require modding bluetooth firmware):
+//   - Is any board nonresponsive (which one?)
+//   - Does either board have a low battery?
+// - Use "shifted keys" hack to make programming symbols easier to type
+// - Add "media" keysyms, Insert, PrintScr, Pause/Break
+// - Dynamically toggle QWERTY or other layouts
+// - See if the henkans placement is at all useful for Japanese speakers, or
+//   abuse different keysyms
+// - Overlay a 10key numpad somewhere
+// - Mod a speaker onto my receiver and enable tones
+// - Mod more indicator LEDs onto my receiver
+// - Do something with Num/Caps/Scroll lock?
+// - Improve tri-layer behavior
