What is the new Windows 10 search shortcut?
Using 
+F you used to be able to open a search dialog.
I recommended WinKey+F this as an alternative to the start menu search, which didn't work anymore for a blind person using a screen reader. He told me that after trying this, he got "something about signing in and when I hit enter, nothing happens". Starting a Windows 10 VM and trying myself, it turns out they changed this to the "Feedback Hub".
What is the new shortcut? I tried +F3, F3 by itself on the desktop, and Ctrl+F on the desktop.
An alternative I just thought of while writing this post is two steps: +E to open explorer, then Ctrl+F to focus the search. This seems to work when trying it. Is this how you are supposed to do it now?
In Windows 10, Microsoft has changed shortcut for search to Windows+S. It opens Search tab in Start menu. Alternatively, you can use Search bar in Taskbar or Cortana.
If you want search in Windows Explorer, you can do the following:
- Press Windows+E to launch Explorer¹.
- Press Ctrl+E to put focus to Search field.
- Type search request.
¹ Explorer in Windows 10 opens Recently Used folders and files. I'm not sure whether searching here will find all the files in your computer. You might want to configure Explorer to open This Computer folder by default.
