Add a hotkey to load all file in current containing folder

[mwestphal]

Would it be possible to add a key that allows to add all files from a folder after opening one file out of it? E.g. I drop a file from a folder, then - while looking at the file - consider to look at all. Also (it's a shame to say that, but) as I am forced to use win at work I got used to its picture viewer that by default allows to browse all files in the same folder.
