Another way, that doesn't need dired to be running is to use emacs'
directory expansion. That is,

(expand-file-name ".")

gives the full pathname of the current directory. This is a bit hacky,
to be honest, but I don't know a neater solution. Tassilo's solution now
becomes:

binFMnhVukGk1.bin
Description: application/emacs-lisp

Personally though, I wouldn't use the let form at all, and would just
write the following:

binxSH5d50p4k.bin
Description: application/emacs-lisp

Finally, since this now works outside of dired, you can use a global
keybinding if you want - how about:

(global-set-key (kbd "C-<f12>") 'my-browse-dir)

(of course, C-<f12> isn't necessarily what you want to use).
