When an action is selected In the Task Builder's Available Actions Pane and the user completes the parameters on the General tab, its properties are displayed in the Steps Pane. All actions and activities encompass a Description tab within its properties that allows you to modify and fully customize the description of any step when it appears in the Steps Pane. This feature can be used to convey more detailed information or operation instructions to other team members. Adding a custom description overwrites the general description in the Steps pane.
Custom step description is only supported in Visual mode, not in AML mode, which displays the steps in AML (AutoMate Markup Language) view.
To specify a custom description for a step:
Suppose you have added a Dialog action with the message "This is my message" in the message box.
Double-click the step. The Properties dialog box appears.
Click the Description tab.
Select the Use custom description check box and then type the desired description.
Click OK. The new description is then displayed in the Steps pane in place of the original description.
The step functions the same way as before, it's only the description of the step in the Steps pane that has changed.
A similar way to document instructions, enter notes, reminders or other important information directly onto the steps of a task is by adding Comments.
