Hello kathy shepard,
It is possible that an update contributed to the change, but there is not enough information to confirm this. A more likely setting to check first is Chrome’s Caret Browsing, which can be switched on accidentally with the F7 key. Turning it off may restore the usual Home and End page-navigation behavior.
While viewing a webpage, press F7 once. If Chrome displays a Caret Browsing prompt, choose to turn it off. You can also open Chrome Settings > Accessibility and make sure Navigate pages with a text cursor is turned off.
If that does not help, open an Incognito window and test the Home and End keys there. If they work in Incognito, a Chrome extension may be intercepting those keys. Temporarily disable extensions, especially keyboard, scrolling, accessibility, or shortcut-related extensions, and test again.
You could also test the same webpage in Microsoft Edge. If Home and End work there, the issue is likely limited to the current Chrome profile. In that case, creating a new Chrome profile may provide a practical workaround without changing Windows settings.
Please let me know how it goes after trying these steps, and I'll be glad to continue looking into it with you.
