The number of the current subtitle is displayed as a black figure in the info column. Between subtitles the next number is shown in a lighter color.
Whenever a subtitle is inserted or deleted all subtitles are automatically and instantly renumbered. Pac, rac, or 890 files with gaps between numbers or inserted numbers (eg. 10a, 200b) are always renumbered as a series of integers when opened by TitleVision. The work file and files that are saved with the TitleVision program always consist of gapless, serially numbered subtitles.
