In File Explorer windows, I have figured out how to select contiguous items with the onscreen keyboard by selecting the first item, holding Shift, and using the left/right arrow keys. Using my finger and lassoing works too.
How does one select multiple noncontiguous items? In other versions of Windows, this is accomplished with the Ctrl key, but I can't get anything like this to work on my surface. I've been trying to use View>Item Check Boxes but that does not seem to work either. What am I missing?
Go into list view (bottom right) and then press in front of each item - a checkbox will select those items you choose.
