Hi, I'm looking for a Bluetooth keyboard that works well with Macs and has the Insert/Delete/Home/End/Page Up/Page Down keys. This Macbook is used mostly for software development, and having to press Fn-Up to page up is killing me! I really like the slim feel of my other computer's wired Apple extended keyboard; the plastic Dell keyboard I've been using with the MBP is so thick and tall that it hurts my wrists. Any suggestions for a BT keyboard? Looks like most of them just contain the standard keys. Logitech makes some, but it seems they require a wireless receiver dongle, and I kind of don't want to waste a USB port on that. Thanks for the help!
