The Hit List handles URLs with 'thehitlist' scheme in the following manner:
Look up by UID
Show the task or group with the UID in The Hit List application.
Look up by Group Name
Show group with name 'group2', that is a subgroup of 'group1'.
Add new task to group with name 'group'.
thehitlist:///<group>/tasks?method=POST&index=<n>&title=<title>¬es=<notes> You can only add to lists and the Today group.
This has to be 'POST' for task creation.
Title of the new task
Notes to include in the task
The URL to include in the task notes
Dates can be specified using the shorthand value that The Hit List application understands. For example, "6/4", "June 4, 2010", "4" (4th of the next month), "wed", "4d" (in four days), "today", "t" (today), and so on and so on. If you add a task to the Today group, the start date gets automatically set to today.
Example values are 30m, 0.5h 1d, and so on.
Priority can range from 0 to 9 where 0 is no priority
An index value of n will insert to that index in the group or task. Index of -1 is a special case where it will add to the end of the list, the default is 0.
