I have had my Surface Pro about a year, using the touch keyboard. Recently I purchased the Type Cover 2 (which is what my local Best Buy now carries). However, it has a few differences, specifically the increase volume and decrease volume keys are not there. On the Type Cover 2, the first three are dim, brighter, and mute -- without any way to increase or decrease the volume. In addition, the dim and brighter keys seem to do nothing at all either. Does this mean that this is the wrong keyboard for this version of my Surface? If it is, I can take it back. Is there another Type Cover for the Surface Pro (not number 2) with those functions? Or is there a keyboard combination that will do the same things I need? If there is another keyboard I have to get, I can probably get it at my local MS store where I purchased the Surface. Thanks in advance.
