Most browsers support navigation using keyboard shortcuts called AccessKeys, defined by the website you’re visiting.
On Windows, you can press ALT + an AccessKey.
On a Macintosh, you can press CONTROL + an AccessKey.
The Opera browser takes a different approach: you press Shift+ESC and then the AccessKey.
Using Firefox under GNOME, I use ALT + SHIFT + AccessKey.
Please note that in Internet Explorer for Windows, if the AccessKey refers to another page, pressing ALT + an AccessKey will only shift focus to the link. You must then press Return to follow the link. In Windows, ALT + some key is also used for menu shortcuts.
The following AccessKeys are defined in Instiki
ALT-E: edit the current page
ALT-U: go to Recently Revised (mnemonic: “updates”)
ALT-H: go to Home Page
ALT-A: go to All Pages
ALT-S: save the current page
ALT-C: show or hide changes; cancel editing the current page
