OK - I got this to work for a single task but would I would like to have it work for a selection of tasks - is this possible?
Also, please let me know if you think the following can be cleaned up and made more efficient.
Thanks.
Code:
tell application "OmniFocus"
set dateToday to (current date)
set theTask to the value of the first item of the selected tree of the content of document window 1 of document 1
set start date of theTask to dateToday
end tell
