Is there a way to quick enter project Task/Milestones

I am working on several project plans (over 100) and it is VERY CUMBERSOME trying to enter in all the tasks and milestones into Zoho. Is there a way to update the tasks and milestones directly from that page without having to click on the task, then click on EDIT, then select the date from the calendar...

Keyboard entry and tabbing would be great rather than having to rely on the mouse so much.
