### <a name="detach-keys"></a> Override the detach sequence (--detach-keys)
Use the `--detach-keys` option to override the Docker key sequence for detach.
This is useful if the Docker default sequence conflicts with key sequence you
use for other applications. There are two ways to define your own detach key
sequence, as a per-container override or as a configuration property on your
entire configuration.
To override the sequence for an individual container, use the
`--detach-keys="<sequence>"` flag with the `docker attach` command. The format of
the `<sequence>` is either a letter [a-Z], or the `ctrl-` combined with any of
the following:
* `a-z` (a single lowercase alpha character )
* `@` (at sign)
* `[` (left bracket)
* `\\` (two backward slashes)
* `_` (underscore)
* `^` (caret)
These `a`, `ctrl-a`, `X`, or `ctrl-\\` values are all examples of valid key
sequences. To configure a different configuration default key sequence for all
containers, see [**Configuration file** section](cli.md#configuration-files).
