Shortcut Plus

Example:  This shows how to define two shortcut profiles bound to shortcuts

    // Shortcut Plus Toggle
    {
        "keys": ["alt+`"],
        "command": "toggle_shortcut_plus",
        "context": [{"key": "toggle_shortcut_plus"}],
        "args": {"profile": "MyProfile1"}
    },
    // Shortcut Plus Toggle
    {
        "keys": ["ctrl+alt+`"],
        "command": "toggle_shortcut_plus",
        "context": [{"key": "toggle_shortcut_plus"}],
        "args": {"profile": "MyProfile2"}
    },

Example: This shows how to create shortcuts that execute only in a given shorcut profile
         The first is bound to Myprofile1 and shows a dialog when all selections are empty
         and the escape key is pressed.

         The other is bound to MyProfile2 and shows the inverse when escape is pressed.

         "shortcut_plus_test" is command only for testing.  You can use any command you want.

    // Shortcut Plus Test
    {
        "keys": ["escape"],
        "command": "shortcut_plus",
        "context":
        [
            {"key": "shortcut_plus:MyProfile1"},
            {"key": "selection_empty", "operator": "equal", "operand": true, "match_all": true}
        ],
        "args": {
            "command_type": "window",
            "command": "shortcut_plus_test",
            "args": {
                "msg": "All selection are empty!"
            }
        }
    },
    // Shortcut Plus Test
    {
        "keys": ["escape"],
        "command": "shortcut_plus",
        "context":
        [
            {"key": "shortcut_plus:MyProfile2"},
            {"key": "selection_empty", "operator": "equal", "operand": false, "match_all": true}
        ],
        "args": {
            "command_type": "window",
            "command": "shortcut_plus_test",
            "args": {
                "msg": "All selections are not empty!"
            }
