The shortcut key for Editing task (ENTER / RETURN) does not work when you are actually viewing a task. This makes processing more difficult than it needs to be, and forces me to use the mouse to click the Edit button.

Overall the keyboard shortcuts need improvement when within the task. There are several fields where the user has to keep remembering different approaches to each field. Priority is a good example - after 2 fields (Project, Context) where I can type any relevant letters and the system will show matching entries, on Priority I then have to press Enter, which gives the priority list, but I can't arrow up/down, I have to type the initial letter of the name. Very confusing.
