It is possible to zoom in and out by pressing CTRL (or on Mac) and using the scroll-wheel on the mouse.
Nodes can be selected by clicking on them (which toggles them on and off), or by dragging the mouse to create a lasso selection (figure 12.8).
It is possible to clear the current selection by pressing on an empty region of the canvas.
When nodes are selected, they will stay in a fixed position. This can be helpful when manually adjusting the layout, for instance, to prepare the tree for publication (figure 12.9).
The following actions are available from the buttons at the bottom of the view:
- Select Sequence Types in Other Views: selected sequence types will be selected in other views that support it. Note that if nodes are collapsed, all the sequence types in a collapsed node will be selected in the other views.
- Create MLST Sub Scheme: This makes it possible to create a new scheme based on the selected sequence types.
