Keyboard shortcuts have been part of the HTML standards since 1997.
I know they work with Mozilla and because they are so old they
should also work with all other browsers but I wouldn't know because I
don't use anything else
;-). To activate the shortcut, simply type "alt-e" (or "control-e", on
Windows). This should click on the link for you.
UPDATE: I hear that these keyboard shortcuts don't work with IE6 on
Windows.
