I'm having a strange keyboard problem on Windows 11. The L, M, P, and apparently K keys won't enter characters in search boxes or title fields, although they work normally in the main post editor and elsewhere. It has been happening for several weeks and seems limited to one website. I've already restarted the computer several times. Has anyone experienced this, and what should I try?

First test the keyboard in a simple editor such as Notepad, including the Shift keys. If those letters fail there too, the keyboard may need replacing. If they work normally, the problem is probably limited to the browser or a particular site.
This sounds like a browser or site-data issue, especially since the keys work in the post editor. Clear the site’s cookies and cached data, then restart the browser. A recent browser update can sometimes cause odd behavior in specific input fields.

I tested it on another device and the keyboard works normally there. The issue only affects the search and title fields on this site, so the hardware seems fine.
