Once I started messing with System Events I got to here pretty fast:
-------------------------------------------------------------------------------------------
tell application "System Events"
tell application process "Notes"
set selectedRow to first row of table 1 of scroll area 1 of group 1 of splitter group 1 of window 1 whose selected is true
tell selectedRow
its properties
end tell
end tell
end tell
-------------------------------------------------------------------------------------------
Okay; this works for selecting a row:
-------------------------------------------------------------------------------------------
tell application "System Events"
tell application process "Notes"
set selected of row 1 of table 1 of scroll area 1 of group 1 of splitter group 1 of window 1 to true
end tell
end tell
-------------------------------------------------------------------------------------------
I've got to fiddle with this some more to suit the person I'm working with but am reasonably happy with my progress so far.
(Not happy that Notes' AppleScript dictionary lacks some of the most basic niceties, but that's par - and let's please not get into another angry tirade on-list. I'll file a bug, but I bet it'll be a dupe.)
