Optimize
This command has a different effect depending on whether you select it from a node, an XGroup or
the XPresso Editor.
If Optimize is selected from a node’s context menu, the node is scaled to the smallest size at which its
name and ports are visible.
If Optimize is selected from an XGroup’s context menu, the XGroup is scaled to the smallest size at which
all its nodes and XGroups can be seen.
Select Connected
This command selects the next connected XGroup or node.
Disable
Use this option to disable or enable the selected nodes and XGroups. This can be especially useful for
testing parts of an expression without having to disconnect wires. (You can also enable and disable
nodes and XGroups from the XPresso Editor’s Edit menu.) Disabled elements have gray sides and are
ignored when the expression is calculated.
If you disable a node or XGroup that is between two enabled nodes and/or XGroups, no values will
be passed through. In effect, the enabled elements will be disconnected from each other. XPresso
elements that cannot be calculated, whether due to disabled elements or incompatible data types,
have a yellow title bar.
Context menu for ports
Using these commands, you can delete ports and wires, rename ports and access the Port Info
window.
To open a port’s context menu:
 Right-click (Windows) or Command-click (Mac OS) on the desired port.
Port Information
This command opens a window containing information about the port, such as its name and data
type.
