Un-choosing and changing chosen states
Chosen states in Lucid are checked with a tick in both the Features Available and Features Chosen lists. To remove a previously chosen state, simply uncheck its checkbox in either list. Note that unchecked states remain in Features Chosen until the key is restarted - this allows them to be easily rechosen if necessary.
To change the value of a chosen numeric feature, click on its edit box in Features Chosen then change the values entered in the Numerics dialog box. To unchoose the feature completely, remove any values from the dialog box and click OK.
