Horizon Client supports the iPad Keyboard Dock and Apple Wireless Keyboard (Bluetooth) external keyboards. Horizon Client supports Apple Pencil as a pointer device on iPad Pro.
Horizon Client automatically detects the iPad Keyboard Dock external keyboard. To use the Apple Wireless Keyboard (Bluetooth) with a remote desktop, you must first pair the keyboard with the client device.
After you pair the keyboard with the iPad, make sure that you do not have the onscreen keyboard in split keyboard mode when you attempt to make the iPad detect the Bluetooth keyboard. To make the client device detect the wireless keyboard, tap the screen with three fingers at the same time, or tap the Keyboard button in the Horizon Client Tools.
Also with the Apple Wireless Keyboard (Bluetooth), after the external keyboard is detected, you cannot use the Horizon Client Tools or three-finger tap to display the onscreen keyboard. You must first deactivate the external keyboard by pressing its Eject key.
The Apple Wireless Keyboard (Bluetooth) does not input the Japanese full-width tilde correctly in remote desktops.
You can input characters for English, Japanese, French, German, Simplified Chinese, Traditional Chinese, and Korean.
Use an English keyboard on your iOS device with a remote desktop that uses a Korean or Japanese input method editor (IME). If you use a Korean or Japanese keyboard on your iOS device and you connect to a remote desktop that uses a Korean or Japanese IME, the remote desktop Windows IME English/Korean or English/Japanese mode is not synchronized with the iOS keyboard locale.
