This is a little extension that opens a GUI filebrowser (Thunar, Nautilus) at the selection, or an image viewer (like gthumb). It is aimed at being the converse of the "open terminal here" in such applications. It can be triggered via a keyboard shortcut or with the CTRL-rightclick menu (selection popup in urxvt language).
The command can can be set via a resource:
URxvt.open-filebrowser.cmd: thunar URxvt.open-imageviewer.cmd: thunar
The code is (very heavily) based on the code of the selection-popup extension.
