The Info Panel contains a Variables tab, providing a powerful place or viewing and editing the variables connected to the currently-selected node.
The panel is divided into sections, one for each level in the hierarchy down to the current node. Each node in this hierarchy has its own set of variables, and these are inherited by the selected node; this means that all the variables visible in the panel are active for the current node.
Finding variables
The controls at the top of the panel provide two different ways to find variables.
Filter mode reduces the list of variables shown, displaying only those whose name or value match the filter term.
Search mode shows the whole list of variables, but highlights those that match the search term.
Shadowed variables
A variable is called shadowed if it is redefined later in the node hierarchy. For example, it could be defined at the family level, and then again in a task within that family; in this case, the variable defined in the family is 'shadowed' by the one in the task and will not be used. Shadowed variables are displayed in grey. They can be shown/hidden with the 'VV' button in the Variables panel. By default shadowed variables are visible in the panel.
In the above screenshot, the Family1 and Family variables are taken from the analysis level, not the 0 level, as the analysis node is closer in the hierarchy to the current node.
