Navigating the Visual Spreadsheet
Zoom in: click on the spreadsheet
Zoom out: shift-click on the spreadsheet
You can zoom in horizontally on any column that has an annotation at the top (gene, chromosome ruler or chromosome coordinates)
Zoom in: Click and drag on annotation
Zoom out: Shift-Click on annotation "click and drag" to zoom-in, "shift-click" to zoom-out on the Annotation View.
If you see subcolumns (ie. there are many probes to one gene), and you want to see just a single column, you will need to build a new column with just that probe. To get the probe name, hover over the subcolumn and alt-click to freeze the tooltip. Copy and paste from the tooltip into the identifier entry box available when adding a new column.
