Key Binds not working in PySimpleGUI App. How to add shortcut keybinds in app?

Question

I am trying to build a simple textbox window which closes after pressing Enter key. I tried several approaches, but none worked. Here's the code:

import PySimpleGUI as sg

init_layout = [
    [sg.Input('', size=(None, 5), background_color='white', border_width=0, key='-MULTILINE-')]
]

init_window = sg.Window('Enter File Name', init_layout, finalize=True)

while True:
    event, values = init_window.read()
    if event in (sg.WINDOW_CLOSED, '\r'):
        break

When I press enter key, nothing happens...

I tried using '\r' and also 'Enter', but that didn't work.

There're lot of ways to do it as following, then handle the event in your event loop.

1. Binding window with the event '<Return>' after window finalized.

# "Return" event
window.bind("<Retrun>", "Return")

2. Binding the Input element with the event '<Return>' after window finalized.

# "-INPUT- Return" event
window['-INPUT-'].bind("<Return>", " Return")

3. Add one hidden Button with bind_return_key=True.

# "Enter" event
sg.Button('Enter', bind_return_key=True, visible=False)

4. Add option return_keyboard_events=True to sg.Window.

# '\r' event or 'Return:13' (It maybe different for different platform)
window = sg.Window('Title', layout, return_keyboard_events=True)
