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.
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 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: 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: scroll right a line scroll up a screen scroll down 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.
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.
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.
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.
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.
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.
In the case of horizontal scrolling, the distance
of a line is about 5% of the view area width.
In the case of horizontal scrolling, the distance
of a line is about 5% of the view area width.
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.
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.
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.
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.
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.
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:
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.
