`nnn` is probably the [fastest and most resource-sensitive](#performance) file manager you have ever used. It integrates seamlessly with your DE and favourite GUI utilities, has a unique [navigate-as-you-type](#navigate-as-you-type-mode) mode with auto-select, disk usage analyzer mode, bookmarks, familiar navigation shortcuts, subshell spawning and much more.

The bookmark prompt also understands the <kbd>~</kbd> (HOME), <kbd>-</kbd> (last visited directory) and <kbd>&</kbd> (start directory) shortcuts.
#### contexts
Contexts (aka _tabs_ aka _workspaces_) serve the purpose of exploring multiple directories in parallel. `nnn` provides 4 contexts simultaneously. The status of the contexts are shown in the top left corner:
- the current context is in reverse
- other used contexts are underlined
- rest are unused
The bookmark prompt understands contexts. To switch contexts press `^B` and enter the context number (1-4).
The first time a context is entered, it copies the state of the last visited context. Each context remembers its start directory and last visited directory.

#### dual-pane or multi-pane
`nnn` doesn't have a native dual-pane or multi-pane mode. On most modern DEs the default terminal emulator handles that. Other options are tmux, GNU Screen, Terminator, Tilix, AltYo and Byobu.
#### change dir color
The default color for directories is blue. Option `-c` accepts color codes from 0 to 7 to use a different color:
