<bp:CommandShortcut Ctrl="true"
                    Shift="true"
                    Alt="false"
                    Key="S"
                    Command="{command: Save()}" />

<p>Last save: {{value: LastSave}}</p>

namespace DotvvmWeb.Views.Docs.Controls.businesspack.CommandShortcut.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string LastSave { get; set; } = "Not saved yet.";

        public void Save()
