Editing text and timing
The subtitle list is the main editing surface: every block with its start, end and text, all editable directly.
Selecting rows
Click a row to select it, Shift-click for a range and Ctrl/⌘-click to add or remove one. Ctrl/⌘+A selects everything, and ↑ / ↓ move through the lines (hold Shift to extend). Selecting a line jumps playback to it. Esc clears the selection.
Editing text and times
Press Enter on a selected line, or click into its text, to type. Enter makes a new line within the subtitle and Esc discards your change; a field saves when you move away. Start and end times are edited the same way: type a timestamp, and an unreadable value reverts. In a time field, the ↑ / ↓ keys nudge the value by 0.1 seconds, or 1 second with Shift.
With a line selected, Set start to the playhead ([) and Set end to the playhead (]) take the time from playback, which is the quickest way to retime a line against the audio.
Formatting
The toolbar has Bold (Ctrl/⌘+B), Italic (Ctrl/⌘+I), Underline (Ctrl/⌘+U) and a Colour picker. While you are typing in a line they act on the words you have selected; otherwise they act on the selected lines. Colour is stored the way the file’s format needs it — an override in ASS, a font tag in SRT and WebVTT.
Search and replace
The Search subtitles… box filters the list by text. The find-and-replace button opens a Replace with field with Match case and Whole word options and Replace all.
Split, merge, shift, new and delete
- Split — cuts the selected block in two at the playhead.
- Merge — combines two or more selected blocks into one, from the earliest start to the latest end.
- Shift — moves the selected blocks earlier or later, keeping their spacing. Enter seconds or a timestamp; a minus sign moves them earlier, and nothing moves before 0:00. Alt+←/→ nudges by 0.1 seconds, with Shift by 1 second.
- New block — adds a block at the playhead. In an empty list, Add first block starts you off.
- Delete — removes the selected blocks (the Delete or Backspace key does the same).
Everything is undoable with Ctrl/⌘+Z and redoable with Ctrl/⌘+Shift+Z or Ctrl+Y.
