Infotip while scrolling with keyboard?

I notice that when scrolling through a list of files using the keyboard (arrow keys), infotips are not displayed; they seem to only be displayed on mouse hover. When you want to browse through a collection of photos and just want a quick preview, it can become cumbersome to hover the mouse over each image. I could use the viewer pane but it takes up screen real estate and in certain cases I only want a really fast preview to identify the photo. I could also switch to thumbnail mode but when I'm working on reordering and organizing photos, I like to be in details or power mode.

Does anyone know if it's possible to have the infotip show up while scrolling though files using the keyboard?

Yes, just hold down the control key.

Got it now - thanks. I do notice however that I can't keep the Ctrl key held down while scrolling. I must scroll using the arrow key, then press Ctrl to view the infotip, but then I must release the Ctrl key to scroll to the next file. I checked in the filetypes editor for any options to configure this behavior but didn't find anything. Perhaps if I change the hotkey to something other than Ctrl it will let me keep the button held down while scrolling. Anyway to change the hotkey?

I don't think the tooltip key can be changed at the moment.
