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.

By default, iSilo™ places a vertical scroll bar on the right so that you can see the current relative location on the current page. If the content of the page is wider than the screen, then a horizontal scroll bar appears along the bottom.


arrow keys and scroll key

The arrow keys have the following scrolling functions:

When not in cursor mode, the scroll key has the same functions as the arrow keys. When used with the Chr key, the scroll key has the following scrolling functions:


scroll behavior

The following paragraphs describe exactly what happens when scrolling by a line or a screen.

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:
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 left 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
In the case of horizontal scrolling, the distance of a line is about 5% of the view area width.

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 page of the Options dialog to change the screen up behavior.

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 page of the Options dialog to change the screen down behavior.


hardware scroll buttons

By default, when you use the Arrow keys or the Scroll key when not in cursor mode, scrolling occurs a line at a time. You can use the
Scroll page of the Options dialog to change the scroll behavior individually for each direction to scroll by either a line or a screen.

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


links

Links, also known as hyperlinks, are words or images in the content of the document that you can select to jump to the target of the link. The item you select 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 select 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

There are two ways to select a link to follow.

using the curosr

If you are in
cursor mode, move the cursor to the link and then press the scroll key select button until the link highlights and then release the select button with the curosr within the bounds of the highlight. If you release the select button 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 Tab key and Shift+Tab keys. Press the Tab key to enter hyperlink mode. Press the Esc key to exit hyperlink mode. When the highlight is over the link you want to follow, press the Enter key or the scroll key select button. When you follow a link, you also exit hyperlink mode.

When not in cursor mode, you can use the up, down, left, and right keys to iterate across the links after entering hyperlink mode.

While in hyperlink mode, if you decide you do not want to follow any of the links currently visible, press the Esc key.

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. You can use the <-- key 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 top right of the title bar, the Back icon appears. This indicates that you can jump back to the last location from where you made the jump using the <-- key.

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 using the Forward command in the Go menu. The Forward icon appears in the top right of the title bar if you ever make a return jump.

You can clear the jump history by selecting Clear history from the Go 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.

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 use the Bookmarks command in the Marks menu to display a list of bookmarks in the current document. Select 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 sub-menu in 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 in the Go to sub-menu of the Marks menu to jump to the top of the current page.

bottom of the page

Use End of page in the Go to sub-menu of 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, use Previous page in the Go to sub-menu of the Go menu 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, use Next page in the Go to sub-menu of the Go menu to go to the top of the next page.

first page

To jump to the top of the first page of the document, use Page number in the Go to sub-menu of the Go menu to get the Go to page number dialog and then press First page.

last page

To jump to the top of the last page of the document, use Page number in the Go to sub-menu of the Go menu to get the Go to page number dialog and then press Last page.

any page

To jump to the top of any page of the document, use Page number in the Go to sub-menu of the Go menu to get the Go to page number dialog, enter the page number in the field, and then press Done.
