Move, resize or delete an annotation ​

Move a bar, change where it starts or ends, or delete it from the timeline.

Before you start ​

Move a bar ​

  1. Press the mouse button in the middle of a bar. The pointer turns into a closed hand.
  2. Drag left or right. The bar keeps its length and follows your mouse.
  3. Drop it. The bar stays in its new place.

Change its length ​

  1. Press the mouse button on the left or right end of a bar. The pointer turns into a two-headed arrow.
  2. Drag the end. Only that end moves.
  3. Drop it. The bar keeps its new length.

Delete a bar ​

  1. Click the bar once. A yellow ring marks it.
  2. Press Delete or Backspace. The bar is gone.

You can also open the bar with a double click, click Delete, then click Delete annotation.

What happens while you drag ​

Ends stop on nearby ends within 8 pixels, so your times line up. Zoom in when you need a value between 2 close ends.

On a track without overlap, a bar refuses to move onto another bar. Turn on Allow overlapping for that track to stack them.

Check it worked ​

Every bar is at least 0.1 seconds long. GRAPE MARS records the whole move or resize as one step, so one undo puts it back.
