I've used Lightroom in the past and my rough understanding is that you quickly go through all of your photos and press X to mark a photo to be deleted, and then delete them all in one go.
Is there anything similar in XnView MP please? Deleting photos separately is really slow (as it is in any program). The closest I've found is to rate photos as 1 star using ctrl + 1 but it's a bit of a faff having to stress like that across the keyboard... I know it's a small thing but I have tens of thousands of photos to sort through, so anything which makes the process just a bit easier would be amazing

Thanks
