Currently, there's no provision for remapping the keyboard shortcuts. Maybe later...

The following are currently mapped

• ctrl-alt s = Search
• ctrl-alt m = Home
• ctrl-alt r = Recent
• ctrl-alt b = Bookmarks
• ctrl-alt h = History
• ctrl-alt ? = Help (note that ? = shift-/)

Also, on certain pages, letters and arrows will allow you to navigate through the listed items. Enter will take you to the selected item. Currently set up are:

• All of the SiteList pages (Bookmarks, History, Recent, Draft, Recent Edits)
• Any list of site contents

On certain pages, keys are mapped to give you key-only control. Here's a list:

Editing:

• Alt-s - save via ajax (note this doesn't work for new items, only items that have been saved before)
• Alt-Shift-s - same as clicking the save button (works on new items).
• Alt-w - toggle "Writing Mode"
