From 4b02ebae717ccac8085030c6168175c88060d92b Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Tue, 17 May 2005 11:53:42 +0000 Subject: [PATCH] Keyboard shortcuts for Twiddle: abcdABCD in line with the notation Gareth and I have been using to analyse the game, and also the number pad. They don't work sensibly for all sizes, but they'll be handy for the most common ones.
