    Not in any browser or PDF viewer I have ever used. Just middle-click anywhere on the page to show a four arrow cursor, then drag in the direction you wish to pan/scroll the page/image.

    Try loading a large image in a browser to see how it works.

    My apologies. You are quite right. I should have explored it further. I have never seen any instructions on how to use it. That may be because I don't know what the feature is called.

    Yes, I do think it would be a useful tool in Irfanview and if it could be made to work in fullscreen too, you could also use it to discover when there are hidden scrollbars that have changed the function of the hotkeys.

    I have forwarded the suggestion to Irfan Skiljan. Let's see what he has to say.

    Irfan Skiljan is looking at it, but thinks it might be difficult.

    If a program generates the whole scrolled image (in memory), the fast scrolling can work ... but it needs memory for the whole image/page.

    I cannot see that fast scrolling would appear any different, in terms of speed, to what it is at present. Using the right hand mouse button the image can be dragged across the screen very quickly. I do not think that anyone in this thread is asking for it to move any faster than that, just to keep moving at that speed all the way to the far edge. I think that the slow scrolling when the cursor is close to the four arrow cursor is more of an issue in Irfanview since, with resampling on, movement appears very jerky.

    It is my opinion that resampling should always be turned off automatically while scrolling is in progress and not turned on again until the scrolling has finished. The user cannot appreciate the improved resolution of the resampled images while the image judders across the screen. The smoother motion when resampling is turned off more than compensates for it.

    A simple multiplier would help a lot.
