Ctrl+Del function and word area selection problem solving inquiry

When deleting using Ctrl+Del in Toad for Oralce v14, special characters such as ,"' are also deleted.
In v12, only spaces were removed when using Ctrl+Del .
Additional note) If ,"' is added to Additional Word Chars, it will not be deleted even if you use Ctrl+Del. However, if you double-click a word to select it, ,"' is also designated as a block area.

In Toad v14, as in Toad v12, is there a way to set Ctrl+Del to remove only spaces and to select only words when selecting words?
