"""
This module creates a tabbed window that displays hotkeys and key chords.

The hotkeys are read from two text files, "hotkeys.txt" and "keychords.txt".
The hotkeys are displayed in two tabs, "Hot Keys" and "Key Chords".

The user can switch between the tabs using the "Alt+1" and "Alt+2" hotkeys,
and toggle between the tabs using the "Alt+n" hotkey.

The window is created using PyQt5, which must be installed for this class to work.
