It happened overnight, 2 nights ago - I'm not sure what happened, but I've tried spraying compressed air, lifting up the keys and pushing hard, toggling from side to side, pushing down hard on the plastic membrane, and applying heat via a hair dryer.
Any suggestions for what I can do? I feel like in the very worst case then I could download some software program to rewire function+0 to 'o' and function+- to 'i'?
