Click the scrollbar of browser by a button in keyboard

Question

In Chrome or Firefox or Microsoft Edge, is there any way to map a keyboard button to "press the scroll bar"? In this way, I could just press a button and move the mouse to achieve the scroll function

Answer 1

To achieve the scroll function by moving the mouse I guess you're referring to the auto scroll feature. In this case just press the middle mouse button (which is the scroll wheel in most modern mice, it's clickable) and move the mouse

If you're talking about the thing that happens when you click the mouse in the trough of the scroll bar then it's the same thing you get when you press PageUp/PageDown or Space/Shift+Space (or Arrow Up/Arrow Down in environments where right click is page movement and left click is line movement by default)

Edit:

To press some button then move the mouse to scroll without autoscrolling just use ScrollAnywhere

Scroll page without touching scroll-bar!

Press Middle (Right / Left) mouse button anywhere on the page to scroll just like with scrollbar.

Features also:

• "grab and drag" scrolling
• customizable scrollbars!
• the Momentum auto-scroll

The same add-on is also available for Chrome and other Chromium-based browsers

Answer 2

No, there is no such keyboard shortcut to drag the scrollbar. You only could try to explore some other ways for scrolling.
