# Configuring a Source Tightening

Changes made to tightening programs in any section need to be actively applied by clicking the Apply button in the bottom right corner of the GUI. Alternatively, changes can be undone by clicking the Undo button in the same location.

When navigating away from the section where changes have been made (by using the Back, Home or Result button), the user will be presented with a warning pop-up where the changes can also be applied or undone. The user cannot proceed without applying or undoing changes.

1. Go to the Sources menu, then select Tightening on the left navigation.

2. Click the plus icon in the top right of the workspace.

3. Give the Source Tightening a name and select the correct Selector mode (Control or Confirm, depending on what is required).

4. By default, only one editable Identifier number will be available when creating a new Source Tightening. At the bottom of the screen, click the plus icon to add more.

5. Give every item an identifier number

   If a socket selector is used, the identifier numbers will correspond to the positions in the socket selector, i.e. Identifier number 1 corresponds to socket number 1 in the socket selector.

6. Choose a tightening program to link to each identifier number by clicking on Program and choosing from the list of tightening programs.
