following The following are ways to select items in the viewer window using a mousethe pointer tool.
To do this: | Do this: |
|---|---|
Select a single annotation. | Click on it. |

Select a single graph. | Click on its handle - the rectangle at the left inside the main view window. |

Select multiple annotations or graphs. | Drag the mouse through a region to select all enclosed items. For graphs, the drag should include the graph handle. A drag must begin in the empty area, not on top of any annotation or in the coordinates track.You can use shift-click or shift-drag to select additional items. Tip: IGB reports the number of selected items in the lower left corner. Use this to count aligned sequences in an alignments track. |
Select a sequence region. | Drag along the axis of the coordinates track to select a set of genomic residues. To select residues, the drag must begin in the axis tier. |
Deselect everything. | Click the empty background space in the viewer window. |
Add to the current selection | Shift-click to add individual items or shift and drag to add multiple items. |
