Validation is a process where Manager checks configuration records for errors or for values for which it regards as requiring a warning. The results of this checking are shown by icons next to the field that caused the error or warning, All errors and warnings are also listed in the Error Pane.

By default validation is performed automatically whenever a configuration file is opened and when any field is edited. However, if required, the use of automatic validation can be controlled through the settings on the File > Preferences > Validation tab.

The icons used for errors and warnings are as follows. These are shown in the error pane and also next to the related field in the details pane. In the details pane, the error or warning description is shown when the cursor is hovered over the icon.
