## Deleting Tasks

To delete a task:

1. Select the task (click the row)
2. Press **Delete** or right-click → **Delete Task**
3. A confirmation dialog appears

### Confirmation Dialog

The dialog shows:

* Task name being deleted
* Number of dependent tasks (if any)
* Option to **Delete** or **Cancel**

### Cascade Behavior

* **Deleting a task with dependencies:** The dependencies are removed; child tasks are re-parented (promoted)
* **Deleting a summary task:** Child tasks remain but are unindented (promoted to parent level)
* **Deleting a non-critical task with float:** No impact on project finish date

### Delete Confirmation

## Undo and Redo

### Keyboard Shortcuts

* **Ctrl+Z** — Undo last action
* **Ctrl+Y** — Redo last undone action

### Undo Stack

* GlidePath maintains a history of recent actions (default limit: 50 actions)
* You can undo/redo multiple times
* History clears on project close/reload (if not auto-saved)
