JumpBar: Scroll to Top & Magnifier is a lightweight desktop utility that helps you instantly scroll and zoom within any app window — without using the keyboard. Use on-screen floating buttons or your middle mouse button to scroll to the top or bottom of Excel, Notepad, browsers, and more. Trigger a circular magnifier near your cursor to help you focus on small text or detailed elements. JumpBar doesn’t modify any Windows settings and doesn’t run background services. It simply overlays a transparent control that sends system-wide input — designed for people who work with long documents, spreadsheets, or visually dense apps. ✔ Scroll to top/bottom using on-screen buttons ✔ Middle-click scroll and magnifier trigger ✔ Toggleable magnifier near your mouse ✔ Adjustable size, position, and opacity ✔ No background processes or setup ✔ Works with most Win32 desktop applications ⚠️ JumpBar is an independent app and is not affiliated with or endorsed by Microsoft.
