On-Screen Insert Key

This project is a simple Windows application that allows users to send the "Insert" key to a selected window from a list of currently visible windows. The application enumerates all visible windows, populates a combo box with their titles, and sends the "Insert" key to the selected window when a button is clicked.

Features

• Enumerates and displays visible windows in a combo box.
• Sends the "Insert" key to the selected window.
• Simple and easy-to-use graphical interface.
