While translating in French, I saw that a couple of original English shortcuts 
letters were not found in the string:

Item "Normal Space|w"
Item "Half Quad Space (1/2 em)|k"
Item "Non-Breaking Half Quad Space (1/2 em)|E"

I updated these to

Item "Normal Space|e"
Item "Half Quad Space (1/2 em)|S"
Item "Non-Breaking Half Quad Space (1/2 em)|k"

with hopefully no shortcuts conflicts.
