A command line is also provided and operates in conjuction with the directory panels to make it much more powerful than a regular CLI. Other features include built in support for archives, Unicode file name support, a built in viewer and editor with syntax highlighting, and Unicode text file support.

The keybindings are similar to those of other console programs like vim, mutt, or ncmpcpp, so the usage will be intuitive and efficient.
