 ## **PROTOCOLS**

 ## Keyboard {#Keyboard}
 *Defined in [fuchsia.ui.test.input/text.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.ui.test.input/text.fidl;l=10)*
 <p>A tool to inject keyboard events into Input Pipeline.</p>
 <p>Please extend as necessary.</p>


 ### SimulateUsAsciiTextEntry {#Keyboard.SimulateUsAsciiTextEntry}

 <p>Simulates input of the set of keystrokes required to type <code>text</code>,
 as if on a US QWERTY keyboard.</p>
 <p>US ASCII text get mapped to the corresponding key presses.
 For example <code>a</code> gets mapped into a press and
 a followup release of the key <code>a</code> on the US QWERTY keyboard.  Also,
 <code>A</code> gets mapped into a press of the <code>Shift</code> key, followed by a press
 and release of <code>a</code>.</p>
 <p>For convenience, the <code>\n</code> and <code>\t</code> get converted into <code>Enter</code> and <code>Tab</code>
 keys respectively.</p>

 ## KeyboardInputListener {#KeyboardInputListener}
 *Defined in [fuchsia.ui.test.input/text.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.ui.test.input/text.fidl;l=39)*
 <p>A tool for client applications to report text input to interested parties
 (e.g. a test fixture).</p>
 <p>NOTE: The reporter is the <em>client</em> of this service.</p>
 <p>Canonical usage is for a test to inject text via fuchsia.ui.test.input.Keyboad,
 and wait for the client under test to report back that it received the injected
 text via fuchsia.ui.test.input.KeyboardInputListener.</p>
 <p>NOTE: This protocol is implemented by OOT code. When adding new methods here
 the methods MUST be annotated with <code>@transitional</code> at introduction time.</p>


 ### ReportReady {#KeyboardInputListener.ReportReady}

 <p>Notify that the client is ready to receive text input. Clients that need
 to complete their setup to be able to continue with testing should call
 this method, so that the listener can wait until they are ready to
 proceed with testing.</p>
