In "Fit Height" and Continuous modes, the vertical position of the page drifts when turning pages using PageUp/PageDown

[rakunavi]

Hello all,

Various shortcut keys exist for turning pages forward or backward. While they may be assigned to other functions depending on the situation, the following shortcut keys are generally available.

1. Left, Right
2. Ctrl+Left, Ctrl+Right
3. PageUp, PageDown
4. Shift+Space, Space

When displaying the sample file in “Fit Page” mode and Continuous mode with sufficient horizontal space in the page view, using any of these four shortcut keys will turn pages forward or backward by one page at a time. However, when displayed in “Fit Height” mode and Continuous mode, shortcut keys #1 and #2 turn pages by one page at a time, while shortcut keys #3 and #4 cause the displayed page position to drift.

• Video.webm

If there is sufficient horizontal space in the page view, it seems there should be no difference in page turning behavior whether in “Fit Page” or “Fit Height”. Why does this discrepancy occur?

When displaying content precisely aligned to the page height in “Fit Height” mode, it seems natural for users to expect the PageUp/PageDown keys—whose names explicitly include “Page”—to turn pages exactly one page at a time.

Thank you for taking the time to read this message.

Best regards,
