Multi-window View Settings and Operations in Notepad++

# 1. Introduction

In modern operating systems, multi-window viewing has become a very common and necessary feature. With multi-window viewing, users can view and operate multiple windows simultaneously, enhancing work efficiency. This article will introduce how to use the multi-window feature in different operating system environments, including opening multi-window views, switching between multi-windows, closing multi-windows, customizing multi-window layouts, and keyboard shortcuts. Let's step by step to understand these features.

# 2. Opening Multi-Window Views

In this chapter, we will learn how to open multiple window views in a program. Multi-window views can improve the user experience, allowing users to view and operate multiple contents simultaneously. Below is a sample code demonstrating how to open multiple window views in Python using the Tkinter library.

import tkinter as tk

def open_new_window():
     new_window = ***level(root)
     label = tk.Label(new_window, text="This is a new window")
     label.pack()

root = tk.Tk()
button = tk.Button(root, text="Open New Window", command=open_new_window)
button.pack()

root.mainloop()

In this code, we first import the `tkinter` library and create a main window `root`. We then define the `open_new_window` function, which opens a new window view when the button is clicked. Finally, we create a button that, when clicked, calls the `open_new_window` function to open a new window.

Running the above code and clicking the button will pop up a new window view displaying the text "This is a new window". This accomplishes the function of opening multiple window views in a program.

In this way, we can conveniently implement multi-window views, enhancing the interactivity and functionality of the program.

# 3. Switching Between Multi-Windows

In work, it is often necessary to quickly switch between different multi-windows to improve efficiency. Next, we will introduce how to implement the switching function of multi-windows in different programming languages.

#### Python Implementation:

from selenium import webdriver
import time

# Start the browser and open the first window
driver = webdriver.Chrome()
driver.get("***")

# Open a new window
driver.execute_script("window.open('***', 'new_window')")

# Switch to the new window
new_window = driver.window_handles[1]
driver.switch_to.window(new_window)
time.sleep(2)   # Wait for 2 seconds for observation

# Switch back to the first window
driver.switch_to.window(driver.window_handles[0])

**Code Explanation:**
- Use the Selenium library to open two windows and switch to the specified window.
- `driver.window_han
