My sorting is pretty typical from what others are describing. I just wanted to say that I'm amazed at how readable your typing in spite of all those problems. You may be able to Google instructions for how to clean the type of keyboard you have. Some have keys that can be pried out and popped back in (while the devise is off and unplugged, of course). Especially if the computer is near your sewing area, there's all kinds of stuff that can get in there and cause problems. I recently saw an idea - don't remember where. You can use masking tape to cover your keyboard with thin clear vinyl, a piece cut from a plastic bag or parchment paper. Be careful not to cover any air vents and have it loose enough so that the keys move as usual. Haven't tried it yet, but it might help to prevent problems.
