As another option for customization, I have posted here in the past on assigning the same shortcut to multiple macros to get a Keyboard Maestro pane to select the desired macro. Here is the one I use in DEVONthink to create a new document, called with command-n.
As example, you could use this approach with korm’s macro if you use a document type naming convention similar to Merlin Mann’s ‘refx’, ‘ideax’, ‘runx’, etc. Just duplicate the macro for each of the document types that you use, and modify each of them so that when the macro is selected it will default to a specific document type.
