Working with Selection
The following commands are used to work with a selection:
Selects the whole document.
Complexity: constant-time.
Drops the current selection.
Complexity: constant-time.
Inverts the current selection. Selected blocks become unselected, and vice versa.
Complexity: constant-time.
Use this command to add, subtract or overlap the given range with a current selection.
Complexity: from constant-time to linear-time, depending on the current selection.
Drops the current selection and adds all modified document data to the current selection.
Complexity: linear-time, depending on number of document modifications.
Compresses and saves the current selection to a disk file.
Complexity: linear-time, depending on the number of blocks in a current selection.
Loads and optionally merges the selection from disk file with a current one.
Complexity: linear-time, depending on loaded selection complexity and current selection complexity (for merge operations).
