To manage editing character clusters, the CTL language supports both character-based deletion and cell-based deletion. In character-based deletion, the user deletes the separate elements of the character cluster with each press of the Delete key. In cell-based deletion, the user deletes the entire cluster with one keystroke.
The two deletion modes can be assigned to separate keys on the keyboard using translation and resources. For more information, see Step 3 in Section 3.1 CTL Motif Resources.
