Grid toolbars

Both grids have these toolbars. They contain subtitle manipulating buttons:

• Insert subtitle - insert new subtitle before the selected line in the translation
• Remove subtitle - remove the selected subtitle from the translation
• Merge subtitles - merge selected subtitle with next subtitle (append lines of the text, use start timestamp of the first subtitle and end timestamp of the second subtitle)
• Split subtitle - split selected subtitle. In the ask mode, the Split Subtitle dialog is shown. Otherwise selected subtitle must contain at least two lines, the first subtitle will get the first half of lines, the second subtitle the rest. The start timestamp of the second subtitle and the end timestamp of the first subtitle are calculated as average of the start and end timestamps of the original subtitle.
• Search - search for text. Brings up the Search / Replace dialog
• Seek to start / end timestamp - seek the movie to start / end timestamp of the selected subtitle. Useful for checking the audio.
