Solved XFE file manager: how to open file in Vim?

I use x11-fm/xfe as a file manager. Since gvim is no longer avaliable, I want text and markdown files opened in Vim. Since Vim only lives in a terminal window, double clicking the file in XFE should start my terminal (xterm) and then Vim with the file.

Can anyone tell me how to force XFE to do so?

Discovered so, wondering some time why text files weren't opened the usual way. Preferred plain editors/vim anyway because it has no frills.
