I have been placing markers on a model that is made of around 8000 photos, which is not that big compared to other models I work with. As long as I place a new or existing marker on a photo (when everything is already aligned), it works well. But when I accidently press "add marker" instead of place marker, it goes through every single photo and it takes ages. I would simply like to abort adding a marker when it takes a long time by pressing "Esc".
