How You Can Use the Trace Log Portlet
When the Trace Log portlet on the Debug tab is selected, the Run menu provides the following options:
Write Log to File
Writes the current log to a file that you specify. If Lines to Display is n, this command writes at most n lines.
Redirect Output to File
Writes all log data to a file that you specify. Log data is written to the file until you redirect the log output to a different file or you select a different application on the Develop tab.
Clear Log
Clears the data displayed in the Log for Application window. If you have redirected output to a file, this operation does not affect the contents of the file.
Add Message to Log
Inserts a text string into the log at the cursor position
