If you need to enter similar text for a number of images, you can create a template. You can have standard information in the template itself, or you might just have headings to remind you what information you need to record for your images.
To use templates
Use the text editor of your choice (eg. Notepad) to create the template and save it.
With the cursor in the text box, select Edit->Insert Template... from the menu or just press Control-I. A dialog opens to allow you to chose the template. The last template you used should already be selected. Click OK and the template will be copied to the text box. If there is already text in the text box, the template is inserted ahead of the existing text.
