~/Library/Application Support/Quicksilver/Actions/ with the name “in.scpt” (you will probably need to create the Actions folder)using terms from application "Quicksilver"
on process text theText
tell application "Mori"
tell front document
set inFolder to entry named "Inbox"
make new entry at end of entries of inFolder with properties {name:theText}
end tell
end tell
end process text
end using terms from

set clipboardText to the clipboard as text
make new entry at end of entries of inFolder with properties {name:theText, note:clipboardText}
