Access Keys
Some browsers support jumping to specific links by typing keys defined
on the WEB site. In the Windows environment, you can press ALT
+ an access key followed by ENTER ; in the Macintosh
environment, you can press Control + an access key.
The home page and all supporting pages define the following access keys:
- Access key 1 Go to the home page
- Access key 2 Go to the help page
- Access key 3 Go to the contact page
- Access key 4 Go to the tool page
- Access key c Skip to the page content
- Access key 0 Go to the Accessibility Statement page (this
page).
The tool page defines the following access keys:
- Access key b Focus on the Back button
- Access key r Focus on the Reset button
- Access key n Focus on the Next and Get Carbon
button
- Access key s Focus on the Selection Box Depending
on the step the s key will focus on the state, county, soil, hydric,
rotation, or tillage boxes.
- Access key p Focus on the the parcel information
boxes
- Access key p Focus on the parcel units information
boxes
Internet Explorer on Windows
IE has to some extent supported accesskey since
version 4.0. On IE 4.0, if the value of that attribute is a letter of
the English alphabet, then using the corresponding keyboard key together
with the Alt key will focus on the element where the attribute appears.
On newer versions, the support is wider; e.g., IE 5.5 supports digits as
access keys, too. For details, see Microsoft's documentation of
"accelerator key" or
accesskey on IE.
Note that on IE, using the access key typically only gives
focus to the element. If the element is a link, it is not followed. The
user can thus move to a link by hitting the Enter key when the focus is
on the link.
Beware that on IE, the implementation is not consistent; for example,
for a radio button, focusing toggles its setting.
Links
Many links have title attributes which describe the link in greater
detail, unless the text of the link already fully describes the
target (such as the headline of an article).
Whenever possible, links are written to make sense out of context.
Many browsers (such as JAWS, Home Page Reader,
Lynx, and Opera) can extract the list of links on a page and allow
the user to browse the list, separately from the page. To aid this,
link text is never duplicated; two links with the same link text
always point to the same address.
There are no javascript: pseudo-links. All links can be
followed in any browser, even if scripting is turned off. There are
no links that open new windows without warning.

Netscape 4.7x is partially supported. For best results, upgrade to a
more recent browser or, if that is not an option, disable the use of
JavaScript and style sheets in the preferences
