Mouseovers on heap annotation tracks result in a tooltip displaying information about the range of values under the mouse, and their associated row and column in the heatmap.
For Predicted Alignment Error (PAE) matrices, the only form of heatmap annotation currently supported by Jalview, both the vertical and horizontal positions in the heatmap correspond to positions in linked 3D structures and the associated sequence in the alignment - so clicking any position in a heatmap will select columns in the alignment corresponding to the selected row(s) and column under the mouse.
