To remove intronic or intergenic regions from the display or to view only custom specified regions, click the multi-region button under the track image. For human assemblies hg17 and later, you may also replace a section of the reference genome with an alternate haplotype chromosome in order to view annotations upstream and downstream of the sequence. For more information about the multi-region feature see the multi-region help page.

The first time the annotation track window is displayed, or after the Genome Browser has been reset, the size of the track window is set by default to the width that best fits your Internet browser window. If you horizontally resize the browser window, you can automatically adjust the annotation track image size to the new width by clicking the resize button under the track image. To manually override the default width, enter a new value in the image width text box on the Track Configuration page, then click the submit button. The maximum supported width is 5000 pixels.
-The item labels (or track label, when viewed in dense mode) are displayed to the left of the annotation image. The width of this area is set to 17 characters by default. To change the width, edit the value in the label area width text box on the Track Configuration page, then click Submit.
-The annotation track image may be adjusted to display text in a range of fonts from AvantGarde, Courier, and Times. To change the size of the text, select an option from the text size pull-down menu on the Browser Configuration page, which you can find under the top blue "Genome Browser" menu by clicking Configure. Once you have made your selection, which can also include style click submit. The text size is set to "12" and "Helvetica" by default.
-The chromosome ideogram, located just above the annotation tracks image, provides a graphical overview of the features on the selected chromosome, including its bands, the position of the centromere, and an indication of the region currently displayed in the annotation tracks image. To hide the ideogram, uncheck the Display chromosome ideogram above main graphic box on the Tracks Configuration page.
-The light blue vertical guidelines on the annotation tracks image may be removed by unchecking the Show light blue vertical guidelines box on the Track Configuration page.
-The track and element labels displayed above and to the left of the tracks in the annotation tracks image may be hidden from view by unchecking the Display track descriptions above each track and Display labels to the left of items in tracks boxes, respectively, on the Track Configuration page.

+When the Next/previous item navigation configuration option is toggled on, on the Track Configuration page, gray double-headed arrows display in the Genome Browser tracks image on both sides of the track labels of gene, mRNA and EST tracks (or any standard tracks based on BED, PSL or genePred format). Clicking on the gray arrows shifts the image window toward that end of the chromosome so that the next item in the track is displayed. Similarly, the Next/previous exon navigation configuration option displays white double-headed arrows on the end of any item that extends off the edge of the current image. Clicking on one of the white arrows shifts the image window to the next exon in the indicated direction, unless the image window interrupts an exon, in which case the window shifts to the edge of the current exon. If the image window happens to be within a 5' or 3' UTR, then clicking the arrows shifts the image window towards the start or end of the next coding region, not the end of the exon.
