Design Goals

Don't change the display of information between editing and displaying edited information (i.e. wysiwyg).
Don't require user to leave or change their context to edit information.
Make it clear that changes can be made and to what.
Give users edit tools that make sense for their specific context. Don't clutter with every possible edit tool.
Smooth & easy keyboard interaction.

Allow users to easily see and use the edit tools they need (as opposed to giving them many tools that aren't relevant or useful most of the time).
Give users feedback and confidence about what is saved.
Give users an easy way to back out (i.e. undo change & error recovery).
Instant editing
Allow user to complete their task without being distracted by software or losing train of thought (i.e. while they are reading text they can easily make a quick edit).
Give users access to information they need to complete their task (i.e. information on other pages, etc.).
Assist users in not making mistakes with their edits. If mistakes are made, we need to give them an easy way to identify and correct.
