Specifying Access Keys
Access keys are specified in HTML using the accesskey attribute. The value of an element’s accesskey attribute is the key the user will press (typically in combination with one or more other keys, as defined by the browser) in order to activate or focus that element. Though the accesskey attribute sets the key that can be pressed it does not automatically notify the user of the bound access key. One convention is for the page author to show the access key value by using the tag to underline the a letter in the link’s text corresponding to the accesskey assigned. For the link below a user would press Alt+H on Internet Explorer, Ctrl+H on a Mac (the command key can give undesired results) and ⇧ Shift+Esc+H on Opera to be directed to index.html.

*:after {content:' '}Emphasize isn’t necessary, but can be useful to the user. It helps them identify which key to press to navigate to where they want to. Another possible way of displaying which accesskeys do what is to create a page with all the accesskeys displayed. Or the webmaster could do both. Another option for the end user is to install a user script such as FireFox Access Bar for GreaseMonkey.

Famous quotes containing the words access and/or keys:
“The last publicized center of American writing was Manhattan. Its writers became known as the New York Intellectuals. With important connections to publishing, and universities, with access to the major book reviews, they were able to pose as the vanguard of American culture when they were so obsessed with the two Joes—McCarthy and Stalin—that they were to produce only two artists, Saul Bellow and Philip Roth, who left town.”
—Ishmael Reed (b. 1938)
“And yet we constantly reclaim some part of that primal spontaneity through the youngest among us, not only through their sorrow and anger but simply through everyday discoveries, life unwrapped. To see a child touch the piano keys for the first time, to watch a small body slice through the surface of the water in a clean dive, is to experience the shock, not of the new, but of the familiar revisited as though it were strange and wonderful.”
—Anna Quindlen (b. 1952)
