Insert enables you to work with template files. This means you use files with standard components like headers, footers, disclaimers, forms, etc and simply insert them in existing files you've opened in the editor. The insertion will take place at the position of the cursor. Remember, you can define a template directory for each project in the Project Manager. This will save you time as it will allow Insert File to open directly with the needed directory.

While uploading you'll be able to track progress by watching the preselected files window go empty or by following the messages in the logwindog at the bottum.
