I'm using Emacs 24.5.1 in Mac OS X.
Recently I had to input
£ frequently so I changed my input source from U.S. to British. With British keyboard, Option+3 will yield
# in other editors, however, this doesn't work in Emacs since
M is special keystroke in Emacs.
How can I insert
# in Emacs in Mac OS X with Brithsh keyboard?
