Removing Gap at the Left

To remove a gap in the Sanger Reads Editor, select the next character or gap after the gap you want to remove and press Backspace. You can also select Edit -> Remove gap at the left in the context menu or go to Actions -> Edit -> Remove gap at the left.

If there is a region of gaps or it is the beginning of a read, by holding the Backspace key, you can shift a Sanger read to the left. To shift the read to the right, hold the Space key. For more information, see the Inserting Gap chapter.

You can always cancel the changes by pressing Ctrl+Z.
