### Using keyboard events within focus groups
In addition to the **container.KeyFocusNext** and **container.KeyFocusPrevious** options that allow moving keyboard focus through all leaf containers, the user can also assign containers into separate focus groups.
#### [container.KeyFocusGroup](https://godoc.org/github.com/mum4k/termdash/container#KeyFocusGroup):
The **container.KeyFocusGroup** assigns a container into a focus group identified by a number.
#### [container.KeyFocusGroupNext](https://godoc.org/github.com/mum4k/termdash/container#KeyFocusGroupNext):
The **container.KeyFocusGroupNext** is like the **container.KeyFocusNext** option, but the keys configured using this option only move the keyboard focus within a single focus group. The key only takes effect if the currently focused container is a part of the same focus group.
#### [container.KeyFocusGroupPrevious](https://godoc.org/github.com/mum4k/termdash/container#KeyFocusGroupPrevious):
The **container.KeyFocusGroupPrevious** is like the **container.KeyFocusPrevious** option, but the keys configured using this option only move the keyboard focus within a single focus group. The key only takes effect if the currently focused container is a part of the same focus group.
