To Do List

This is a Python program that creates a to-do list manager using the Tkinter library. The program has a main window with a toolbar and a menu with various options such as importing tasks from a file, saving tasks to a file, and displaying instructions and keyboard shortcuts. The program also allows users to add, delete, and mark tasks as completed, and displays these tasks in separate lists which the user can view by selecting either the deleted tasks or completed tasks buttons. The program also includes features such as the ability to delete tasks with the backspace/delete key and add tasks by pressing enter.
