Answer : The issue happens when you open a RDP connection. Just bring the RDP window in foreground and press Alt + Enter . The issue will disappear on all other windows too Source: How to Fix Alt Gr Key Not Working. In my case left Shift + Caps Lock + AltGr helped. I have no idea what it does, but it works. Some utility programs can also "steal" the keyboard stroks. In my case it appeared that the VirtualDesktopManager resulted in non-functional AltGr, so I could not write [ and ] .

Answer : Yes. To add a Bluetooth keyboard, go to Settings > Accessories > Manage Bluetooth Devices. For a non-Bluetooth wireless keyboard to work, it would probably have to have its own wireless receiver that would plug into the console via USB. It also supports USB keyboards. From page 31 of my PS3 owner's manual: Using a USB keyboard You can enter characters using a USB keyboard (sold separately). While the text entry screen is displayed, if any key on the connected USB keyboard is pressed, the text entry screen will enable you to use the USB keyboard. Hint You cannot use the predictive mode when using a USB keyboard. Unfortunately, it looks like there aren't many games that natively support keyboard/mouse. I did find the Eagle Eye, a third-party adapter that allows you to use a USB keyboard/mouse in lieu of a controller regardless of whether or not the games supports it. Although you can use a mouse and keyboard, you can't play...

Answer : There is now a blog entry about Taking Screenshots in a Snap . It's built into Mac OS. ⌘ + ⇧ + 3 captures the whole screen ⌘ + ⇧ + 4 captures a custom rectangle (click and drag over the screen region you want to capture) ⌘ + ⇧ + 4 then space captures a specific window (move the mouse cursor over the desired window, then click) Press esc to cancel. Screenshots are saved onto your Desktop and timestamped. Holding control in addition to any of the sequences above causes the image to be copied instead of saved to the desktop. By default the image format is png . However, you can change the format by typing in the Terminal : defaults write com.apple.screencapture type image_format killall SystemUIServer Where image_format is one of jpg , tiff , pdf , png , bmp or pict (among others). If you omit the second line, you will need to log out and in again for the change to take effect. The settings for the shortcuts in the system preferences are ...

Answer : Yes. This is definitely possible, requiring no modifications or drivers on the PC. As the OP mentions, the USB identification on the phone end is ultimately done in software (in this file https://github.com/android/kernel_msm/blob/android-msm-2.6.35/drivers/usb/gadget/composite.c), and it could be modified to identify itself as a standard USB keyboard. This change would require a couple of things. A modified kernel with a patched USB driver An Android app that could talk to some interface exposed by the modified USB driver. There was a paper published a couple of years ago (titled Exploiting smart-phone USB connectivity for fun and profit ) that described using a phone to brute-force desktop login screens. The method they used involved making the phone appear as a USB keyboard. This doesn't exactly answer your question, but it might help in your use case. Maybe you want to have a look at InputStick. It'll be a USB thumb drive that you pair to Android via...
