Hi, recently we were asked to add a keyboard shortcut to add a task at the beginning of the current list, keeping the current context (the list can be focused/filtered).
To do that, add a task as usual, at the current selection, and then use mm shortcut to move the new task to the current list. Basically, this is mmEnter.
This will place the list item at the very beginning of the current list, and you will stay in the current context.
Hope it will help someone 
(and I need to add more characters to post this)
