I have coded button shortcuts in Tk via bind and underline in Tk but I can't find how to do it in sg? - I have simulated it in Python code but I would like the Ampersand(&) feature(& precedes the hot key, which is bound to Alt) as implemented in the Qt port(VB also does this).

Code To Duplicate

#    
#    Tkinter code:

# top.title("Kookie")
# top.bind("<Alt_L>""<k>", lambda event: kookie_click())
# top.bind("<Alt_L>""<x>", lambda event: exit_click())
# top.configure(background="darkblue")
#    .
#    .
#    .
# self.kookie.configure(command=kookie_click)
# self.kookie.configure(text='Kookie')
# self.kookie.configure(underline="0") # underlines 'k'
# self.kookie = tk.Button(top)
#    .
#    .
#    .

Your tkinter code maybe show something, but not enough and not correct.
Here's my code to demo shortcut for sg.Button if it's correct for your issue.

import PySimpleGUI as sg

sg.theme("DarkBlue3")
sg.set_options(font=("Courier New", 20, 'bold'))

layout = [
    [sg.Button("kookie", size=(10, 2), key='button1'),
     sg.Button("exit"  , size=(10, 2), key='button2')],
]
window = sg.Window('Title', layout, use_default_focus=False, finalize=True)
button1, button2 = window['button1'], window['button2']

# Binding key event
window.bind("<Alt_L><k>", "ALT-k")
window.bind("<Alt_L><x>", "ALT-x")

# Set index for underline
button1.Widget.configure(underline=0, takefocus=0)
button2.Widget.configure(underline=1, takefocus=0)

while True:
    event, values = window.read()
    print(event, values)
    if event == sg.WINDOW_CLOSED:
        break
    elif event in ("button1", "ALT-k"):
        print('kookie !!!')
    elif event in ("button2", "ALT-x"):
        break

window.close()

Thanks! Jason, all good.

I've BARELY started to use hotkeys in my PySimpleGUI programs. Only recently I Tweeted an example of how 1 line of code, a Window.bind call, can add a hotkey to your program.

@jason990420 has once again come through here with an excellent example of this. Thanks SO much Jason... 🙏🏼

I will be adding this technique to the cookbook.

The place I'm going to immediately be adding it is the Demo Browser. I want to hotkey the searches so that a hotkey will move the focus to the correct search box.

To get from Filter, where it starts, to Find, I have to press tab 5 times

I just added this code while typing up this comment.

When I created the window:

    window.bind('<F2>', '-FOCUS FIND-')

and insdie my evnet loop:

        elif event == '-FOCUS FIND-':
            window['-FIND-'].set_focus()

There may be a better way, but it works! Still learning about PySimpleGUI and how to use it.

Thank you two for the inspiration!

Definitely will be adding this capability all over the place now that I've got it on my batman toolbelt!
