 Changelog:
 
+## Feb 5, 2016:
+
+* A whole new design for the symbol layer. Specifically:
+  * Put the minus, underscore, and semicolon right in the homerow for the right hand
+  * Parens are in better places for me
+  * The arrow keys now send Ctrl-PgUp and Ctrl-PgDn, for switching browser tabs with the arrows when in symbol layer
+  * Tab (right-hand outer thumb key) now does double duty to toggle symbol layer when held down
+  * Backspace (left-hand outer thumb key) now just toggles symbol layer (I wasn't using it as a backspace)
+  
+
 ## Jan 19, 2016:
 
 * Made J into dual-action key (Alt when held down), to make Alt-tab more ergonomic.
