Subject: 1.10.5 64-bit (Mar 15 2026) : Alt+pgup,Alt+pgdn error

XnView: MP 1.10.5 64-bit (Mar 15 2026)
OS: Windows Libformat 7.232 (Windows)

<Short description of the problem.>

Effect: When I changed the settings from using PgUp/PgDn to switch between files to using Alt+PgUp/Alt+PgDn for navigating to previous/next files, the program failed to correctly distinguish between PgUp and PgDn. Regardless of whether I scroll up or down with the mouse wheel, it always moves to the next file.



To reproduce:
1. PgUp/PgDn = Page Up/Page Down keys
2. switch Alt+
3. ...
Actual behaviour (bug): <Current wrong behaviour of XnView>

using Alt+PgUp/Alt+PgDn for navigating to previous/next files, the program failed to correctly distinguish between PgUp and PgDn. Regardless of whether I scroll up or down with the mouse wheel, it always moves to the next file.

Expected behaviour: <Expected, correct behaviour of XnView>

I expect scrolling up to go to the previous file and scrolling down to the next file.

you have changed Wheel ALT => 'Previous/next file'?

I think there's a problem with the list design options. Would you expect the settings shown in the image below to work?

感谢你们的回复。

幸好现在的AI技术非常好。我的疑问都可以比较好的表达出来，你提出的意见很好。我用英语的截图可能会更加便于你们理解。

请你们设置到我截图的Alt+PgUp和Alt+PgDn为上一个文件/下一个文件的方式后。

看看你们能不能复现出我说的问题，就是无论我上划滚轮还是下划滚轮都是下一个文件。

谢谢你们耐心的回复。

"Thank you for all your reply.

Fortunately, current AI technology is excellent, which helps me express my issues clearly. Your suggestions are very helpful. I will use English screenshots, as they might be easier for you to understand.

Could you please set the shortcuts for ‘Previous File’ and ‘Next File’ to Alt+PgUp and Alt+PgDn respectively, just like in my screenshot?

After making these settings, please see if you can reproduce the issue I mentioned: whether I scroll the mouse wheel up or down, it always switches to the ‘Next File’.

Thank you for your patience and support."

Yes。

I can reproduce

Alt+Wheel scroll Up/Down

• in Viewer (with OPs settings)
  it always navigates to the next file

• in Browser (with default settings)
  it always scrolls down
