Windows 10: How to Pause a Slideshow in OneDrive

OneDrive has a useful slideshow feature but there seems to be no way of slowing down the display speed or pausing the display. Am I missing something or is this another product where MS failed to consider how their product would be used?

How do you manually pause the slideshow in Windows 10 photo app?

The new photos app in windows 10 is quite good but I can't find how to manually pause the slideshow. You press F5 to start the slideshow and you can press the left and right keys to manually advance / reverse the slides, but you can't pause it (the spacebar
used to pause it in the old app but this doesn't seem to work in Windows 10). So if you are looking at a photo of particular interest, it will automatically move to the next photo and you have to keep using the back arrow to return to the photo of interest.
So how do you pause the slideshow on a single photo and turn off the automatic advance feature?

 

How do you manually pause the slideshow in Windows 10 photo app?

Sorry - this is not helpful. All that F5 does is takes you our of the slideshow so all the other icons reappear and you lose the full screen view. All I want to know is how you pause a slideshow so it stays in full screen. It's such a basic requirement
of a slideshow that you can pause it but I simply cannot find out how you do it. Without pause the app is, of course, completely useless for giving slideshows as a part of a lecture, etc. So how do you do this simple thing? Surely it can't be that hard!

I would also like to know how to pause a slideshow so that it stays in full screen. The Windows 7 Photo Viewer was able to do this this, why doesn't the windows 10 version of this software have this feature? When will this feature be available in the Photos
app?
