I might do something like this:
Code:
tell application "OmniWeb"
activate
tell application "System Events" to keystroke "c" using command down
set pageTitle to name of front browser as text
end tell
set mySelection to the clipboard
tell application "OmniOutliner Professional"
set myDoc to first document whose name contains "webclips"
tell myDoc
set myRow to make new row at end of rows
set value of cell 2 of myRow to pageTitle as text
set value of note cell of myRow to mySelection
set note expanded of myRow to true
end tell
end tell
