It is possible to edit the text of a note through Applescript:
on setText(theNote, theText) tell application "Tinderbox 8" tell theNote set value of attribute "Text" to theText end tell end tell end setText
One could call it thus:
tell application "Tinderbox 8" tell front document set theNote to (find note in it with path "/Foo") my setText(theNote, "Hello [[world]]!") end tell end tell
In this case, it would be great if one could say “process that text as if someone typed it in”. Maybe this is dangerous and one should need to be explicit somehow, but this would be useful functionality.
