Tasks in Gmail
Shortcuts for Gmail Tasks seem to be a bit buggy. shift+t adds message to the task list, but the focus never makes it to the task window. There seems to be no way to re-gain focus after. Page refresh with f5 and g, then k does the trick but is not pretty.
g, then k	Go to task window or opens task window (see limitations above)
shift+t	Add message(s) to tasks.
arrow keys	Move cursor up and down in task list.
ctrl+up / ctrl+down	Move current task up and down in task list.

shift+enter	Edit task details, including due date or notes.
shift+esc	Shift the cursor from tasks to Gmail, but only one-way.
esc	Closes Task Window if focus is on it (see limitations above).

The Rest
?	Displays the keyboard shortcuts help menu.
q	Move cursor to chat search.
/	Move to Search Mail field.
shift+n	Update conversation with new messages if there are any.
