"This specification (HTML 3.2?) defines a "new" tag <OBJECT> which subsumes the role of the IBM tag, and provides a general solution for dealing with new media, while providing for effective backwards compatibility with existing browsers. OBJECT allows the HTML author to specify the data, and/or properties/parameters for initializing objects to be inserted into HTML documents, as well as the code that can be used to display/manipulate that data. Here, the term object is used to describe the things that people want to place in HTML documents, but other terms for these things are: components, applets, plug-ins, media handlers, etc."
"The data can be specified in one of several ways: a file specified by a URL, in-line data, or as a set of named properties. In addition, there are a number of attributes that allow authors to specify standard properties such as width, and height. The code for the object is specified in several ways; by an explicit reference, or indirectly by the object's "class name" or media type." W3

A looong time ago, before rats (read mouses) there was this thing called the "Tab Key". It was great, just a few taps with the left pinky and you were where you wanted to go. We have now "pregressed" back to the tab key.
The "tabindex=" attribute takes, as an argument, a number indicating the order of the "focus" of the browser. The objective is to allow the reader to tab around all of the important links on the page and select one with the "enter" key.
The <a> page has been set up for use with "tabindex="

"This is informational only and describes the object specified with the HREF attribute. It can be used for object types that don't possess titles, such as graphics, plain text and Gopher menus." (Microsoft)
"Title is little used or supported and is a Level 1 attribute, but is expected to be the title of the HREF document. RFC 1866 suggests TITLE can be displayed as a margin note or on a small box while the mouse is over the anchor. (Sandia)
"Title=" has suddenly taken on a new role. The objective of HTML 4.0 is to make browsers more user friendly for the handicapped and title= is one of the potential tools. Follow the link for more detail.

"This give the suggested width of a box enclosing the visible area of the object. The width is specified in standard units.

Smooth scaling a small image to a larger size provides an effective solution to reducing the time needed to download an image, offering better subjective results when compared to color reduction.W3
