Key code for an application

Question

When configuring an application in a configuration, there is a field for "Key Code."  Can you explain what this is for and how it works?

Answer 1

This option is available in Configuration details, Application settings tab, when you click a "..." icon to the right of the application.

By using the "Key code" field, you can assign a key to run the application.

This option mostly used on Android TV boxes using a remote control.

The list of key codes is available in the official Android documentation: https://developer.android.com/reference/android/view/KeyEvent  (click the KEYCODE_* link, and use the constant value in that field, for example, use 23 for KEYCODE_DPAD_CENTER).
