A user can browse through the results by using one of the tools in the navigation bar (on the top of the view; Figure 1). Select tracks tool is the topic of a separate section, while the remaining tools are described below.

You can use the Search box to zoom to genomic features that are available in the annotation track. Start typing a search term and Partek Flow will Partek Flow will show you the first 10 suggestions (Figure 52). To select one, use the arrow keys or mouse, or type the full feature name and hit enter.

The Position box enables the user to visualize a region in the genome. Coordinates are accepted in the following format: chromosome:start – end (zero-based). To show an entire chromosome, it is sufficient to enter just the chromosome number. The U-turn icon on the right Image RemovedImage Added takes you back to the original view, i.e. resets the zoom level to the view that was shown when the viewer was first opened.
Next, the mode selector (Figure 63) helps you to quickly navigate through the results.

When pointer mode is activated, the appearance of the cursor will change to an arrow (Figure 4). Pointer mode provides details on any item (e.g. short sequencing read, variant, microarray probe, annotation feature) selected on the canvas. The selected item is highlighted by a green box (Figure 4).

When zoom mode is activated, the appearance of the cursor will change to a plus plus sign ( + ). With the zoom mode on, you can magnify a specific region by positioning the cursor cursor ( + ) to the left of the area of interest and then <left-click> & drag the mouse to the right of the area of interest (Figure 5). When the viewer refreshes, it will come "closer" to the region that was selected (by halving the number of basis displayed on the screen).
