After 25 years of using Apple computers I am stumped! Just read two articles in MacLife; both had tips to fix or improve performance that required pressing or holding down particular keys. One key looks almost like an equal sign in which the upper line is a simple horizontal line but the lower one is a bit shorter with the left end of the line turned up to meet the upper line. I can not press that key because my Mac keyboard has no key like that! What am I missing/ not understanding here? All help appreciated. Dave
