[notabug][helpwanted] Not sure how popup is meant to work ?

I'm making a menu that, ideally would display on the existing terminal output, without the "root" window, it also has key shortcuts for each item.

I tried using add_popup, but on my first try:

The cursor keys didn't work for navigation (is that expected) ?
I couldn't work out a sane way to get a reference to it, so I could attach hotkeys to each item.

In the end, I've used a normal menu, it's not ideal, as the background is there and it's possible to focus the root element.

(My use-case for the hotkeys is a scenario where the screen is sometimes blank).

Here's the for a menu of options code so far - are there some really obvious things I'm missing ?

import re
import sys

import py_cui
from py_cui.keys import get_ascii_from_char

class SimplishMenu:
    # Match any keys in square brackets:
    HOTKEY_REGEX = r'\[(.*?)\]'

    def __init__(self, title, items, row=0, column=0, root=None):
        if root is None:
            root = py_cui.PyCUI(30, 30)

        items = list(items)
        row_span = len(items)
        column_span = max(len(item) for item in items)

        self.menu = root.add_scroll_menu(title, row, column, row_span + 1, column_span)
        self.menu.add_key_command(py_cui.keys.KEY_ENTER, lambda: self.choose_item(self.menu.get()))

        # Hotkeys
        self.menu.add_text_color_rule(self.HOTKEY_REGEX, py_cui.RED_ON_BLACK, 'contains', match_type='regex')
        for item in items:
            self.add_item(item)
        self.root = root
        self.root.move_focus(self.menu)

    def choose_item(self, item):
        if self.menu.get() != item:
            # If item was chosen via hotkey, select it
            self.menu.set_selected_item(item)

        self.root.stop()

    def add_item(self, item):
        hotkeys = ''.join(re.findall(self.HOTKEY_REGEX, item))
        if hotkeys:
            for hotkey in hotkeys.lower():
                self.menu.add_key_command(get_ascii_from_char(hotkey), lambda: self.choose_item(item))
        self.menu.add_item(item)

    def get(self):
        return self.menu.get()

    def show(self):
        self.root.move_focus(self.menu)
        self.root.start()

def choose_option(title, items):
    root = py_cui.PyCUI(10, 10, auto_focus_buttons=True, exit_key=None)
    menu = SimplishMenu(title, items, root=root)
    root.start()
    return menu.get()

if __name__ == '__main__':
    option = choose_option('Main Menu', ['Option [1]', 'Option [2]'])
    print("Chose: ", option)
