The TAB+# to move tasks to specific sections in My Tasks is great… IF you know the number of the section you want to move to.
I had added index numbers to the task sections (as suggested by ShunS here) but I frequently add or rearrange sections in My Tasks so those numbers are never up-to-date.
It would be easier to have an automatic index number at each section to easily reference and use the keyboard shortcut, instead of frequently recounting and reindexing manually.
