DEVONthink has a homely little contextual menu item "Save Title As". All it does is set the title of the record to the text selected within the record. Nothing special. But it does the deed with one click. No cutting and pasting. I've missed it in Tinderbox when working with lots exploded notes I want to quickly rename, usually to words or phrases somewhere in their respective texts.
My new friend AppleScript to the rescue. On my machine all that's needed is a script like this:
Code:on run
set myStampName to "_clp2nam" --name of Tinderbox stamp
activate application "Tinderbox" -- make Tinderbox frontmost
delay 0.2 --Give Tinderbox a little time to get set
tell application "System Events" to tell process "Tinderbox"
set the clipboard to (keystroke "c" using command down)
click menu item myStampName of menu "Stamps" of menu bar item "Stamps" of menu bar 1
end tell
end run
And a stamp (here with unfriendly name "_clp2nam" to remind me it's not usually run from the Stamps menu) with this action:
Code:$Name=runCommand("osascript -e 'the clipboard as Unicode text' ")
If the script is pasted into a Run AppleScript action in the Automator (pick "Service" when Automator asks for document type and then drag Run AppleScript to the right panel and paste over the suggested script) it looks like this:

Then through System Preferences/Keyboard the service can be assigned a keyboard shortcut, like this:

Or the script can be saved in a Scripts folder and called from a scripts menu. On my machine it will run directly via FastScripts and can be assigned a keyboard shortcut there. Without FastScripts, it will still run (without keyboard shortcut) as long as it is saved as an "Application", not as the default "Script".
Haven't figured out why saving as an Application works and as a Script doesn't, or why, unlike many AppleScripts, it doesn't behave well when run from a code note using runCommand() with osascript.
But it's been handy... and, for me, an interesting early success in passing values from Tinderbox to AppleScript and back.
