vifm

vifm is exactly what I've been looking for. A file manager that can be controlled with hjkl, dd, yy and p for cut/copy and paste and even marks for bookmarking files - I love it! It even respects quantifiers before commands. In the vifmrc configuration file you can set up own colon-commands and define simple rules what file types (based on extensions) should be opened with which program. vifm features a trash which is enabled by default, but can be disabled easily by editing the very clean and neat configuration file. Very handy, I used to use pcmanfm exclusively but quickly dismissed it after falling in love with the vim editor and in turn vifm. Thumbs up!
