- Press `Ctrl + H` to open the replace box and replace the specified text.
- In the replace box, enter the text to be replaced and the replacement text. Click "Replace" or "Replace All" to complete the operation.

Below is a Python example code:

text = "Hello, this is a sample text for demonstration."
search_word = "sample"
replace_word = "example"

if search_word in text:
     new_text = text.replace(search_word, replace_word)
     print(new_text)

### 6.2 Customizing Functions and Shortcut Settings

In addition to using plugins, users can also customize functions and shortcuts according to their needs to improve editing efficiency. Below is an example code showing how to customize shortcuts in Notepad:

# Example of custom shortcut settings
def custom_function():
     print("This is a custom function example")

# Bind the custom function to the shortcut Ctrl+Shift+C
keyboard.add_shortcut('Ctrl+Shift+C', custom_function)

In the above code, we define a custom function `custom_function()` and bind it to the shortcut `Ctrl+Shift+C`. This way, users can quickly invoke this function by pressing the corresponding shortcut key when editing text.

By using plugins and customizing functions and shortcuts, users can personalize Notepad according to their needs, enhancing work efficiency and editing experience.
