## Properties

      "key-modifiers"            gint                  : Read

## Signals

## Description

Spice supports sending keyboard key events and keyboard leds synchronization. The key events are sent using `spice_inputs_key_press()` and `spice_inputs_key_release()` using PC AT scancode.

Guest keyboard leds state can be manipulated with `spice_inputs_set_key_locks()`. When key lock change, a notification is emitted with "inputs-modifiers" signal.
