A Keyboard Output acts like a Bluetooth keyboard with a single key.
It can be used to control applications running on nearby computers or tablets. For example:
Press Space to control a game
Press Play/Pause to control a YouTube video
When the output is activated it sends a key press.

You can mimic normal key strokes with timed mode set to 0.1 second.
Play/Pause key behaviour:
The play/pause is different from other keys. Press once to play, press again to stop.
Use timed mode to control media playback duration, ex: 3 seconds of playback.
play/pause may not work with all media players, try using the space key instead
Pairing with a computer
To use a Keyboard Output, your iPhone or iPad must be paired with a computer using Bluetooth.
You can pair with one computer at a time.
Before you start
Make sure:
Bluetooth is enabled on your iPhone or iPad
Bluetooth is enabled on your computer
If the Keyboard Output is not connected, you will see an exclamation mark (!) on it.
Step 1: On your iPhone or iPad
Open the Think2Switch™ app.
Go to the Control tab.
Select a scene that includes a Keyboard Output or add one.
Step 2: On your computer
Open Bluetooth settings on your computer.
Search for nearby Bluetooth devices.
Look for a device called “Think2Switch”.
On some computers, it may appear with your device name (for example, “iPad”).
On Windows, you may need to show all devices or turn on advanced discovery.
Select the device and choose Pair or Connect.
Step 3: Confirm pairing
A message will appear on:
your iPhone or iPad
your computer
Confirm pairing on both devices.
When connected, the Keyboard Output will no longer display an exclamation mark.
This may take a few seconds. Once paired, the Keyboard Output is ready to use.
Keyboard Output not connecting
If the exclamation mark (!) does not go away, the Keyboard Output is not connected.
This usually means Bluetooth pairing needs to be reset.
Step 1: On your computer
Open Bluetooth settings.
Find the device named "Think2Switch".
On some computers, it may appear with your device name (for example, “iPad”).
Choose Remove, Forget, or Disconnect.
Step 2: On your iPhone or iPad
Open Bluetooth settings.
Find the device with your computer’s name.
Tap Forget this device.
Step 3: Check your Scene
Before pairing again:
Make sure your scene includes at least one Keyboard Output
The Keyboard Output should be visible on the Control tab
Step 4: Pair again
Repeat the pairing steps from the previous section.
Once connected, the exclamation mark will disappear.
Compatibility
Keyboard Outputs work with computers that support Bluetooth keyboards.
The following systems have been tested:
Windows 11
macOS Sequoia or newer (with a different Apple ID)
iOS devices (with a different Apple ID)
Important note about Apple IDs
Apple devices (Mac, iPad, iPhone) signed in with the same Apple ID will not show the "Think2Switch" device in bluetooth settings. To work around this:
Use a different Apple ID on the iPhone or iPad running Think2Switch™ app
