The lyrics is made of lines; one line corresponds to one page. Each line holds a set of karaoke syllables, small phonetic units attached to notes. Lines are separated by line breaks.

To navigate or select notes:

  • Select a note in the note sheet.
  • Select a syllable in the lyrics area. The full line is shown.
  • Use cursor keys to move through lines (up, down) and syllables (left, right). The up/down buttons also move through lines.
  • You can jump to the first or last syllable in the line (Home/End) or lyrics (Ctrl+Home/End).
  • Select multiple notes by dragging ranges (mouse button 1) or rectangles (mouse button 2), or by pressing Shift+Up/Down.
  • Selections can span multiple lines.
  • Select the entire line with Ctrl+A, or double-click it, or click its line number.
  • Type a line number in the lyrics area to jump to a specific line.

By default, you select notes by clicking. Hover selections (‘mouse-over’) can be activated in the preferences.

Selections always result in a full-line zoom. If you want to scroll the timeline smoothly without triggering a zoom, drag the background above/below the note sheet, press the left/right arrow buttons, or the H/J keys (+Shift=faster).

  • Select multiple syllables.
  • Drag the line numbers in the lyrics area.
  • Press Page-Down/Up to increase/decrease the number of pages shown
  • Press Ctrl+PageDown/Up to zoom to one page / all remaining pages.
  • Press Ctrl+Shift+PageDown/Up to zoom to one page / all pages.
