As I usually only write English, this is annoying. The backtick/tilde key is subject to similar behaviour. This is not a duplicate of the linked question because the two problems have completely different solutions. This question was caused by an internationalisation setting being activated; that other question was caused by keys being set to dead. I have not attempted to set up my computer to process anything other than English. My keyboard appears to be (in so far as these things are standard on laptops) a standard US qwerty keyboard. How can I stop this happening?
