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

The following are currently mapped

• ctrl-alt s = Search
• ctrl-alt h = Home
• ctrl-alt i = History
• ctrl-alt b = Bookmarks
• ctrl-alt c = Recently Created
• ctrl-alt ? = Help (note that ? = shift-/)
• alt m = Open "More" menu

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:

• Up/Down/Home/End for moving between items. Alphanumeric keys will cycle through items that start with that letter. Left/Right will expand and collapse appropriate items.
• 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"
