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

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. iSilo™ provides many options for scrolling, so you can choose the method most comfortable to you.

using a scroll bar

By default, iSilo™ places a vertical scroll bar on the right for scrolling up and down through the page. It is the default because the scroll bar is the user interface item most used anywhere for scrolling and hence is the most intuitive method. If the content of the page is wider than the screen, then a horizontal scroll bar appears along the bottom for scrolling left and right.

the vertical scroll bar

The vertical scroll bar allows five different scroll operations:
You can position the vertical scroll bar on the left or right of the screen or hide it altogether. To change the setting, use the Interface Options dialog.

scroll up a line:
Tap on the upward pointing arrowhead of the scroll bar to scroll up a line. If the current first line is partially displayed, then it scrolls in to become fully displayed. If the current first line is already fully displayed, then the line above it scrolls in to become fully displayed.

The distance scrolled is in all cases limited to a tenth of the height of the view area. This means that if you have a tall image that you are scrolling in from the top, each time you scroll up by a line, only an amount equal to one tenth of the view height scrolls in each time.

scroll down a line
Tap on the downward pointing arrowhead of the scroll bar to scroll down a line. If the current last line is partially displayed, then it scrolls in to become fully displayed. If the current last line is already fully displayed, then the line below it scrolls in to become fully displayed.

The distance scrolled is in all cases limited to a tenth of the height of the view area. This means that if you have a tall image that you are scrolling in from the bottom, each time you scroll down by a line, only an amount equal to one tenth of the view height scrolls in each time.

scroll up a screen
Tap in the area below the upward pointing arrowhead and above the scroll car to scroll up a screen. By default, when you scroll up a screen, if the current first line is partially displayed, it becomes fully displayed as the last line after the scroll. Otherwise, the line above it becomes the last line after the scroll. This behavior is called full with text align. You can use the
Scroll Options dialog to change the screen up behavior.

scroll down a screen
Tap in the area above the downward pointing arrowhead and below the scroll car to scroll down a screen. By default, when you scroll down a screen, if the current last line is partially displayed, it becomes fully displayed as the first line after the scroll. Otherwise, the line below it becomes the first line after the scroll. This behavior is called full with text align. You can use the
Scroll Options dialog to change the screen down behavior.

scroll to a relative location within the page
The scroll car is the solid rectangle that shows the size and location of the currently displayed content relative to the current page. You can drag the scroll car to scroll to the content at a relative location within the page.

the horizontal scroll bar

The horizontal scroll bar allows five different scroll operations: The horizontal scroll bar does not appear unless there is content on the page wider than the width of the view area. If you set the Scroll Bar option in the Interface Options dialog to None, then the horizontal scroll bar never appears even if the page has content wider than the width of the view area. In this case, you need to use some other method of scrolling horizontally, such as dragging.

scroll left a line:
Tap the leftward pointing arrowhead of the scroll bar to scroll left by a line. In the case of horizontal scrolling, the distance of a line is about 5% of the view area width.

scroll right a line
Tap the rightward pointing arrowhead of the scroll bar to scroll right by a line. In the case of horizontal scrolling, the distance of a line is about 5% of the view area width.

scroll left a screen
Tap in the area to the right of the leftward pointing arrowhead and to the left of the scroll car to scroll left a distance equal to about 95% of the view area width.

scroll right a screen
Tap in the area to the right of the scroll car and to the left of the rightward pointing arrowhead to scroll right a distance equal to about 95% of the view area width.

scroll to a relative location within the page
The scroll car is the solid rectangle that shows the width and location of the currently displayed content relative to the maximum width of the content on the current page. You can drag the scroll car to scroll the content horizontally.


drag scrolling

By default, you can drag your stylus across the screen to scroll the content in the direction that you drag. Using the
Region Options dialog, you can configure which regions and the sizes of the regions on the screen that respond to drag scrolling. Drag scrolling is easy to use and allows you to position content on the screen to the precision of a pixel, but can contribute to screen wear.

tap scrolling

Tap scrolling allows you to simply tap the screen to scroll up or down by a line or a screen. By default, tap scrolling is not enabled. Using the
Region Options dialog, you can configure which regions respond to tap scrolling, the sizes of the regions, and the scroll actions that occur when you tap specific regions. If you configure a region to scroll when you tap it, then you can tap the region once to perform the scroll action once or hold your stylus or finger down on the region to repeat the scroll action continuously for as long as you leave your stylus or finger in the region.

If you have not used tap scrolling before, it may take you a little time to get used to it. However, it is especially useful in situations where it is not easy to use your stylus and must use your fingers.

Note: If you configure any of the regions for an action of screen up or screen down, then please note that the options you set in the Scroll Options dialog determine the specific behavior of the screen up or screen down action.


hardware scroll buttons

By default, iSilo™ sets up the hardware scroll buttons so that if you press the up button, the document scrolls up one screen and if you press the down button, the document scrolls down one screen. You can use the
Scroll Options dialog to change either or both to scroll by a line and even to reverse the scroll directions.

As with the other methods of scrolling by a screen, the Scroll Options dialog determines the specific behavior of the screen up and screen down actions.


hardware jog control

If your device has a jog control which can be rotated up and down, then you can also scroll using it. By default, iSilo™ sets up the jog control so that if you rotate it up, the document scrolls up one screen and if you rotate it down, the document scrolls down one screen. You can use the
Scroll Options dialog to change either behavior to scroll by a line and even to reverse the scroll directions.

As with the other methods of scrolling by a screen, the Scroll Options dialog determines the specific behavior of the screen up and screen down actions.


directional navigator control

If your device has a directional navigator control which can be pressed up, down, left, and right then you can also scroll using it. By default, iSilo™ sets up the control so that if you press Up, the document scrolls up one screen and if you press Down, the document scrolls down one screen. You can use the
Scroll Options dialog to change either or both to scroll by a line and even to reverse the scroll directions.

As with the other methods of scrolling by a screen, the Scroll Options dialog determines the specific behavior of the screen up and screen down actions.

If the currently displayed page displays wider than the width of the screen, you can press Left to scroll left one screen or press Right to scroll right one screen.


links

Links, also known as hyperlinks, are words or images in the content of the document that you can tap to jump to the target of the link. The item you tap 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 tap on 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, hold your stylus down on the link until it highlights and then release the stylus within the bounds of the highlight. If you release the stylus outside the bounds of the highlight, you do not jump to the link's target. Jumping to the target of the link is also known as following the link.

hyperlink mode

In hyperlink mode, you can iterate across the links currently visible on the screen using the up and down buttons or the jog control if available. Use the
button options dialog to assign a button to use to enter hyperlink mode. Use the same assigned button to jump to the target of the current highlighted link. When you follow a link, you also exit hyperlink mode.

While in hyperlink mode, if you decide you do not want to follow any of the links currently visible, tap on the screen to exit hyperlink mode. If your device has a Back or Auxiliary button or if you have assigned the Back action to a button using the button options dialog, you can also press the button to exit hyperlink mode.

On a Sony CLIÉ™ with a Jog Dial™, you can press the Jog Dial™ and hold it in the pushed down position for about half a second to enter or exit hyperlink mode. This allows for one-handed operation for following hyperlinks. Unless the Jog Dial™ has been assigned to some other action, pressing the Jog Dial™ briefly while in hyperlink mode results in following of the current highlighted link.

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 and continue reading from where you left off there. See jump history for how to jump back.

jump history

iSilo™ keeps track of jumps you have made using any of the following methods:
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 in the tool bar, the Back icon appears. This indicates that you can tap it to jump back to the last location from where you made the jump.

iSilo™ provides these methods for returning to the last jump point:

In addition to being able to jump back, you can also jump forward back to the location from where you made a return jump. You jump forward by tapping the Forward icon that appears on the tool bar if you ever make a return jump.

You can clear the jump history by selecting Clear History from the Marks menu. iSilo™ saves the internal 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.

adding a bookmark

Use the
Add Bookmark command on the Marks menu to activate the Add Bookmark dialog to set a bookmark at the current location. See bookmark types for a description of the types of bookmarks you can add to a document.

going to a bookmark

If the document has one or more bookmarks defined, you can tap the Bookmarks icon on the tool bar to display a list of bookmarks in the current document. Tap a bookmark to go to the location that it marks.

editing bookmarks

You can rename, delete, and re-order the bookmarks in a document by using the Edit Bookmarks command on the Marks menu.

bookmark types

Bookmarks come in three types as described here:

Note: For documents in the Doc format, only local and document bookmarks are supported. Documents in iSilo™ format support all three bookmark types. All other document types only support local bookmarks.


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.

unnamed mark

While viewing a document, you can easily mark the current location with the unnamed mark and return to the marked location at any time later. The unnamed mark does not require you to enter a name for it, so it is a quick way to mark the current location. One situation in which you might want to use it is if you want to remember your current location before scrolling through the document to scan for some other information. You can mark the current location with the unnamed mark, scan for the information, and then return to the unnamed mark. You can set one unnamed mark per document.

mark location

To mark the current location with the unnamed mark, choose
Mark Location from the Marks menu.

jump to mark

At any time later after setting an unnamed mark, you can return to the marked location by choosing Jump to Mark from the Marks menu.

page marks

You can jump to the top or bottom of the current page or to any page of the document.

top of the page

Use
Top of Page on the Marks menu to jump to the top of the current page.

bottom of the page

Use End of Page on the Marks menu to jump to the bottom of the current page.

previous page

If the document has more than one page and you are not currently on page one, you can tap the Previous Page icon on the tool bar to go to the top of the previous page.

next page

If the document has more than one page and you are not currently on the last page, you can tap the Next Page icon on the tool bar to go to the top of the next page.

first page

To jump to the top of the first page of the document, tap the Go To icon on the tool bar to get the Go To dialog, and then tap First Page.

last page

To jump to the top of the last page of the document, tap the Go To icon on the tool bar to get the Go To dialog, and then tap Last Page.

any page

To jump to the top of any page of the document, tap the Go To icon on the tool bar to get the Go To dialog, enter the page number in the field, and then tap Go To.
