If a collection is created from one or more entire HTML, DOCX, PPTX, IDML (InDesign), or TXT files, you can preview it using the Preview menu options Show Source Preview [Alt+S] and Show Target Preview [Alt+T]. Source and target content preview are rendered in separate browser windows you can move to any location on screen for convenient comparison of content. You can refresh the target preview to reflect recent changes by selecting Refresh Target Preview [Shift+Alt+T] in the Preview menu.
With the Prompt to select Filename for Multi-file preview setting in the User Preferences you can control how the file for preview is selected from a collection containing multiple files.
If this setting is ON, a dialog with a list of files is displayed where you can click View Preview to launch the preview for a file.
When the Prompt to select Filename for Multi-file preview setting is OFF, the preview of the file associated with the current segment is launched without displaying the list of filenames. For example, if you have selected a segment from the collection and that segment belongs to file XYZ, the preview of file XYZ is launched without prompting a list of filenames.
This setting is OFF by default.
Note: You cannot use the Preview functionality if any of the following conditions is true:
1) The collection is not based on one or more entire HTML, DOCX, PPTX, IDML (InDesign), or TXT files.
2) The collection is copy-protected.
3) The collection is configured to disallow previews.
4) The collection is not assigned to a TM.
