Select Bundle Editor from the application menu, this opens the Bundle Editor. Select Insert TODO List. Select All and Copy the command's code, I've included it here so theres no confusion: […]

It’s worth mentioning that this command does more than insert ‘# TODO’: It uses the comment markers defined for the current language (scope) and if there are block comment markers, it will prefer them, e.g. inserting:

/*
    TODO ‸
*/

If all you need is to (always) insert ‘# TODO edit’ then a snippet is more appropriate: http://manual.macromates.com/en/snippets
