At the family printshop my mother experienced some typing glitches, she would sometimes type "simulate" instead of "stimulate" and "muck" instead of "mark". This led to two disasters, which required us to stop the presses (the pressman was a great proofreader!), In a political brochure: "...will introduce bills to simulate progress..." In a funeral booklet: "...he left his muck upon us all." She asked me to go into computer's master dictionary and patch it to disable the words 'simulate' and 'muck' so it would bring these mistakes to her attention.
