Sorry, but is does not let you scroll when you select the text or try to annotate, here I have tried the demo, it should let you scroll up or down according to the mouse direction as described in the expected behavior ![Recording 2022-10-28 at 21.16.28](https://canada1.discourse-cdn.com/flex031/uploads/pdfjscommunity/original/2X/2/2035943f41919f2cd59d0865c402b0ad20ae7006.gif) ---

Hi there, Please see the attached video, I was able to scroll up and down (using the mouse wheel) while my mouse left click was held down.

Hi Kkim, You are right, it works with a mouse, but it doesn’t work using a computer touchpad on its own. Please check it. Thank! ---

Hi there, Thank you for your response, I just tried with a track pad on a MacBook and it is more tricky but it is doable. What seems to be happening is the system gesture takes precedence occasionally and it sometimes prevents the scrolling with the 2 finger vertical gesture. You might need to ‘reset’ that gesture first and then try scrolling up or down while holding down the first click. I suspect the same thing will happen for Windows.
