In Test Builder, either in 'input' or 'expected results, when editing a value in the 'List of Values' tab | 'Create a new list or query' if you hit the 'backspace' key it will remove character as required. However, if you use the 'Delete' key then the following message is displayed.
'Are you sure you want to remove all selected data values'
The editor does not allow the use of the 'Delete' to remove characters
WORKAROUND
Use the 'Backspace' key to remove characters
STATUS
Waiting for fix in future release of Quest Code Tester for Oracle
