How to assign shortcuts for navigating through images?

[total_annihilation00]

After updating to the latest Beta (the latest one which reads long paths in Images in built-in DataViewer), by a stroke of genius I found out that running in a duplicate portable copy folder, I'am able to cycle through images in built-in DataViewer by pressing the blue Back & Forward Buttons in the Image DataViewer's Menu. I was wondering where the hotkeys for these reside, so I can try changing the keys for this & stop using JPEGView for images. When I press Spacebar it displays the next image in the foler, but the ArrowKeys & PageUp/Down don't work, perhaps re-customizing the hotkeys might fix this ?! (if I knew where they were in the Keyboard Customization)…
P.S: Please allow the Tab Forward/Backward cycling keys to be customized. I don't like Ctrl+Tab/Ctrl+Shift+Tab for cycling tabs, I would prefer Ctrl+PageUp/PageDown instead, if that means clearing the hotkey for the Image cycling (or whatever) Ctrl+PageUp/PageDown I will do that if I have to !

Please allow customizing/ setting hotkeys for back & forward cycling of images & Tabs !!

No wait, Spacebar & Backspace keys work !!!    But it would still be nice to use ArrowKeys for Images in DataViewer Navigation…

yes Backspace/space  go to previous / next image.

Arrow key are used to move the image if you are zoomed in.

Because image viewer is an extension with its own Window it does not fit into the keyboard customization framework that MC have.
But there is plans to rewrite how that works.. then it will support it. but I can't say when that will happen since that is a major change.
