begin-edit-sequence

The begin-edit-sequence and end-edit-sequence methods are used to bracket a set of editor modifications so that the results are all displayed at once. The commands may be nested arbitrarily deep. Using these functions can greatly speed up displaying the changes.

When a editor contains other editors, using begin-edit-sequence and end-edit-sequence on the main editor brackets some changes to the sub-editors as well, but it is not as effective when a sub-editor changes as calling begin-edit-sequence and end-edit-sequence for the sub-editor.

• (send an-editor begin-edit-sequence undoable?) -> void
      undoable? = #t : boolean

  If the undoable? flag is #f, then the changes made in the sequence cannot be reversed through the undo method. This flag is only effective for the outermost begin-edit-sequence when nested sequences are used.
