At the bottom of Figure 4-40, Gnumeric has a tabbed sheet indicator. This is the boxes with the labels "Guppies", "Turtles", "Mermaids", "seahorses" and so on. In workbooks where there are more than one sheet, extra tabs are used to indicate how many sheets are there, and also allows the user to move to another sheet by clicking the proper tab. Each tab is a link to a separate worksheet within Gnumeric. In this figure, the "Turtles" tab has been selected. Gnumeric shows this by making the "Turtles" since the tab is a little bigger and making it overlap the two neighbouring tabs.
On the far right, the two arrows indicate that there are more sheets in the workbook and more tabs for those sheets. Unfortunately, there is not enough space to show them all so Gnumeric displays these arrows. If all the sheets are visible, these arrows will not be displayed. These arrows can be used to scroll the tabs and bring tabs that were hidden into view. This may be a little difficult to understand and work with but becomes easier quickly.
