One of the iPad’s handiest features is its keyboard-shortcut cheatsheet. Whenever you have a USB or Bluetooth keyboard attached to your iPad, just hold down the Command key and wait for a second. An overlay will pop up showing you all the keyboard shortcuts available for the current app.

IK Multimedia’s new iRig Keys is the single perfect accessory for an iOS musician. It combines everything you need into one box, but not in a Homer’s Car kind of way.

If you like mechanical keyboards, you love mechanical keyboards. Their clickety-clack action is way more positive than the soft, short travel of any MacBook or Magic Keyboard, and once you get used to them everything else seems squishy.

You already know that you can in plug a keyboard, or an audio interface, or a camera, using Apple’s Lightning to USB Camera Adapter. But did you know that you can plug in all of those at once? That’s right — by using a powered USB hub, you can hook up as many accessories as you like to your iPad at once. If you ever use your iPad to work at your desk, with a keyboard, then you can use this tip to build your own iPad docking station.
