> # Working with the SequeLink® Manager for z/OS

> The SequeLink Manager for z/OS ISPF panels list items in your SequeLink configuration, allow you to select actions that affect these items, or allow you to view or change attributes.

> For example, you can select a server from the SequeLink Manager for z/OS ServerList menu.

> ### Using the Server Management Tree

> When you select a SequeLink Server, the server management tree appears.

> You can use the server management tree to view or change entities defined within the SequeLink Server, such as:

> - Global settings
> - DB2 interface
> - User ID (UID) maps
> - A SequeLink service and its configuration settings

> Press the TAB key to navigate to the tree nodes on the server management tree.

> To perform an action on a tree node, type the action code at the tree node. To find which actions each node accepts, type `?` beside the node you want information about and press ENTER. For example, when you type `?` beside a SequeLink service, a message appears telling you that the node will accept `D` (Delete), `S` (Select), `/` (Expand or Contract), `+` (Expand), and `-` (Contract).

> Using the Command prompt, you can also type the following commands that affect the server management tree:

> - `EXP` or `EXPAND` expands the tree so that all nodes become visible.
> - `SAVE` saves the current configuration to disk.
> - `REFRESH` rebuilds the tree (if the server is online, the monitor data is refreshed also).
> - `ERRSTK` displays the error stack.

> ### Using the Function Keys

> When working with the SequeLink Manager for z/OS, you can use the function keys listed in Table 6-2.
