| Selections Dialog (for table) |
The first tab of the selections dialog lets the user select observations or variables that belong to one or more classes of a category. The "Direction" combo-box displays whether observations or variables will be selected. In the "Category" combo-box, the user can decide which category to be selected.
Dialog options:
- Select all: Selects all observations/variables.
- Clear: Clears the current selection.
- Invert: Selects all observations/variables currently not selected.
- Select: Selects the high-lighted classes.
- Merge: Merges the current selection with the selected classes creating a new selection.
- Intersect: Selects observations/variables in the selected classes that overlap with the current selection.
- Close: Closes this dialog.
The second tab of the selection dialog is used for selecting observations or variables. The user can choose to only select included observations/variables, all observations/variables, train/test observations and X/Y variables.

The third tab of the selection dialog is used for performing a wildcard search (using for example an asterisk), which will select any matches for the entered expression.
The following are valid expressions for the wildcard search:
| volvo | Will find the exact matches for "volvo" |
| *volvo | The matches will end with "volvo" |
| volvo* | The matches will start will "volvo" |
| *volvo* | The matches will contain "volvo" regardless of position |
| [0-5]* | The matches will start with any number 0 to 5 |
| [a-d]* | The matches will start with any letter "a" to "d" |
| [^a-d]* | The matches will not contain any letter "a" to "d" in the beginning |
For observations, the wildcard search can be used for searching through an observation identifier or any column in the DataSet, which is denoted by a variable name. For variables, the wildcard search can be used for searching through a variable identifier or any row in the DataSet, which is denoted by an observation name. The user can choose which column to search by using the combo-box "Source".
The fourth tab (only available for data tables) provides searching by relationship.
