I try to answer most Mac problems, but here are three things that have me stumped!
With the Apple Camera adapter kit you can plug a USB thumbdrive into your iPad. If you create a folder called ‘DCIM’ you can even trick your ipad into thinking the thumbdrive is a camera and so read photo’s or movies off it. But you cannot save files onto the thumbdrive or load other files from the thumbdrive. If you Jailbreak your iPad you can, so it is possible, it’s just that Apple have disabled the ability to do it. There doesn’t seem to be a way round it. I’ve spent lots of time looking.
You can plug a USB remote clicker into your iPad Apple Camera adapter kit USB port, but it doesn’t work to control Keynote. Plugging in a keyboard into the USB will control keynote, but a remote doesn’t. So again this seems to be a feature Apple have disabled. I cant’ find a way round it.
After you log in to the Apple Store there is no way to log out. You can shut the safari window but when you open it you can still access your purchase history etc. You can quit Safari, but when you re-launch some items such as your shopping cart are still accessible from the history. Lot’s of forums, no answers. So the best I can come up with is don’t use the Apple Store from a public computer!!!
With regard to logging out of the Apple Store: wow! On the other hand, if you try to actually do anything like change your password or credit card info, the site asks you for your password again, so there is some security there.
The clicker thing.. A clicker is just a small keyboard, and the clicking keys might be a period or a tilde or whatever else makes sense in the world of Microsoft. When I bought a laser pointer/presenter from the mac store, I very quickly found out that if Keynote was not in presentation mode and an image or text were selected, then pressing the whiteout button replaced image/text/whateverelse with a “w”. In Powerpoint presentation mode, pressing w whites out the screen. So the presenter is a mini keyboard with 4 keys that needed remapping to commands that make sense to Keynote. I downloaded Banjo (think it was from the App Store, but not sure) and shortly afterwards remapped the W , the B, the . (period) and whatever the other command was. It was 3 or 4 years ago and I do not recall the details.
Anyhow, your clicker keys might just need remapping with Banjo.
