Details Panel
The Tables details panel has tabs for displaying different details about the selected table.
Table - Columns
The Columns tab lists all the columns for the selected table. It also displays each column Data Type whether or not the column accepts Null values, column attributes (such as length, precision, scale), Default value, and column comments, if any. You can change the length, precision, scale display to
"NUMBER(10,5)" through the Toad Option | Schema Browser | Show
Column Length Info with Column Data Type setting.
The dropdown default is Show no comments. The other choices in the dropdown are Column Comments and Table Comments which show the comments in an overlay panel at the bottom of the details panel. You can type directly into this panel to edit the various comments. To save the comment edits, just select a different column or table.
Primary Key columns are indicated by PK column numbers in the PK column. A label to the right of the Add and Drop column buttons in the details panel displays the Primary Key column name(s).
You can multi-select columns, press <CTRL>C to create a comma-delimited list of columns to the windows clipboard and paste the selection into an editor.

Toad
Table - Referential
The Referential tab displays a hierarchy of tables and how the selected table is referenced by other tables and references other tables. This display is based on the existing foreign key constraints from table to table.
Remember, "+" on the keyboard expands one branch of the hierarchy, and
<CTRL><SPACE> expands the whole tree. Pressing the asterisk key, "*" will fully expand the current node.
On each node of the hierarchy, there is a chain symbol for standard referential and a scissors symbol if the reference is Cascade on Delete.
Circular references, such as EMPLOYEE.MANAGER_ID referencing
EMPLOYEE.EMPLOYEE_ID, are captured; so you cannot drill down in the hierarchy endlessly (for example, emp_id is referenced by manager_id, which references emp_id, which references manager_id, and so on).
You can select an item in the list, press <F4> and get a popup window describing the object in detail.
Table -Used by
The Used By tab shows the objects that reference the selected table such as views, triggers, functions, procedures, and packages.
Here, the CUSTOMER table is selected in the objects panel. The Used By tab in the
details panel shows that the CUSTOMER table is used by the Demo.Sales view.
