By default, you can drag your finger across the screen to scroll the content in the direction that you drag. Drag scrolling is easy to use and allows you to position content on the screen to the precision of a pixel.
One common use of links is in a table of contents, whereby it is handy for each item in the table of contents to be a link to its content so that you can simply follow an item to jump to the content. This is much easier than having to search for the page or location where the content starts.
Usually, a textual link has a visual indication such as a dotted underline to indicate that it is a link. But it is possible for a link to not have any such indication if the author styled it as such.
This allows you to easily jump back to recent jump points. If you have jumped anywhere, then the Back button in the tool bar becomes enabled, indicating that you can tap it to jump back to the last location from where you made the jump.
In addition to being able to jump back, you can also jump forward back to the location from where you made a return jump. If you have jumped back from anywhere, then the Forward button in the tool bar becomes enabled, indicating that you can tap it to jump forward.
You can clear the jump history by selecting Clear History from the Marks sub-menu of the menu. iSilo™ saves the jump history across document closes and opens. Note that this saved information does not include the history of jumps to external documents.
