Subject: Unequal: stop ignoring keys 'h' and 'm' while cursor active.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=dc688b1f238fd7c343426b76d120e7ab40aa9668;p=sgt-puzzles.git

Unequal: stop ignoring keys 'h' and 'm' while cursor active.

At least, so long as 'h' and 'm' are not "numbers".
