Toolbar details

• Play starts or pauses the song in the editor.
• Undo and Redo cover chart edits.
• Anchor lists obstacles on the beat they appear, not the beat they are stored on. With it on, changing Countdown keeps that appear-beat fixed.
• The Select button changes label as you go: Select sets the start beat, Set Range confirms the end beat, Cancel drops the selection. See Range Selection and Editing.
• Tips shows keyboard shortcuts. Hover a button to see its shortcut.

The end of the editable beat

The chart ends at End Beat. That beat and the beats after it are marked in red on the Beat Grid. The player cannot move past End Beat, and nothing is scored after it.
