navigation

To move through a document to get to the content you want, you do such things as scrolling, following hyperlinks, and using bookmarks. iSilo™ provides many ways to navigate through a document:

scrolling
links
jump history
bookmarks
marks

scrolling

Scrolling involves a sequential movement either up or down through the content of a page. For example, if you read a novel, you may scroll down line by line as you read or you may read a full screen of text then move on to the next screen of text.

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.

links

Links, also known as hyperlinks, are words or images in the content of the document that you can follow to jump to the target of the link. The item you follow is also known as the link's source. In a well-designed document, the author will have interspersed relevant links throughout the content of the document so that the person viewing the document can easily jump to other relevant or interesting parts of the document.

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.

following a link

To jump to the target of a link, just tap it.

returning from a link

Whenever you follow a link, iSilo™ adds the location of the link's source to the jump history. So after you follow a link and are done reading the content at the link's target, you can immediately return to the location from where you followed the link by tapping the Back button

in the tool bar. You can then continue reading from where you left off.

jump history

iSilo™ keeps track of jumps you have made using any of the following methods:

Jump to the unnamed mark
Jump to a named bookmark
Follow a link
Use the Home tool bar button to go to the home page.
Use the Previous Page button in the Go To panel to go to the previous page
Use the Next Page button in the Go To panel to go to the next page
Use the Go To panel to jump to a location on the page
Use the Go To panel to go to any page
Use the Top of Page button in the Go To panel to go to the top of the page
Use the End of Page button in the Go To panel to go to the bottom of the page

For each such jump, iSilo™ remembers the point from where you made the jump. It can remember up to 16 jumps within a given document and up to eight jumps to external documents.

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.

bookmarks

A bookmark marks a location in a document and has an associated name. You can mark various locations within a document with bookmarks and easily jump to any of those locations at any time simply by selecting the desired bookmark from a list. Some documents may also already have predefined bookmarks. To access the bookmarks list or to perform any bookmark operation, tap the Bookmarks button

in the tool bar to display the Bookmarks panel.

Local bookmarks are stored in the iSilo™ settings folder of your device. If you transfer a document to another device, local bookmarks do not travel with the document.
Document bookmarks are stored in the actual document. If you transfer a document with document bookmarks to another device, those document bookmarks also travel with the document.

marks

While bookmarks provide a method for associating a name with a location in a document, marks provide additional methods for going to specific locations in a document.
