### Override the detach sequence
|
||||
|
||||
If you want, you can configure an 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).
