Based on Eink-UpDown by Sonny Zhao. Disable page-turning animations for Chrome globally (applies to (Shift+) Spacebar and PgDown/PgUp keys). Note: If the "Allow access to file URLs" option is enabled in Tampermonkey's Manage Extension settings, it will also work for local PDF reading. However, this script does not affect frames within the browser.
