[I'm new here, if I've posted this in the wrong forum, I'm sorry!]
Somehow, my keyboard (a Gateway FX laptop, American layout, Windows Vista Home Premium SP2, 32-bit), whenever I type ", ', `, ~ or ^ and a vowel, it comes out with a letter with an accent, such as '+a=á or ^+u=û. It suddenly started doing this, out of the blue. My questions are:
1) Is it possible to switch off/on this setup?
2) Is it possible to add new characters to be inserted when a letter combination is typed?
Thank you.
