X-devonthink-item link from PDF Expert (with page number)

Thanks for your reply! @zeitlings

I’ve tried to create a Keyboard Maestro macro to make it as a workaround.

Where the AppleScript used was derived from Script: Open DEVONthink record for PDF Expert tab:

-- Copy the page number in PDF Expert
tell application "System Events"
	tell process "PDF Expert" to keystroke "g" using {command down, option down} -- open go to page modal
	tell application "System Events" to keystroke "c" using command down
	delay 0.5
	tell application "System Events" to key code 53 -- esc
end tell

-- Open DEVONthink record for current PDF Expert tab
-- Source: https://discourse.devontechnologies.com/t/script-open-devonthink-record-for-pdf-expert-tab/47243
tell application "System Events"
	try
		tell application process "PDF Expert"
			tell window 1
				set theFileName to value of attribute "AXTitle" & ".pdf"
				if theFileName starts with "* " then set theFileName to characters 3 thru -1 in theFileName as string
			end tell
			set PID to unix id
		end tell
	on error error_message number error_number
		if the error_number is not -128 then
			display alert "System Events" & space & error_number message error_message as warning
			return
		end if
	end try
end tell

set theOpenFiles to (do shell script "lsof -p " & PID)

set convertedOutput to (do shell script "iconv -t UTF8-MAC <<<$" & quoted form of theOpenFiles)

set theLines to paragraphs of convertedOutput

repeat with thisLine in theLines
	if thisLine contains theFileName then
		set thePath to characters (offset of "/" in thisLine) thru -1 in thisLine as string
		exit repeat
	end if
end repeat

tell application id "DNtp"
	try
		set theDatabases to databases
		set theResults to {}
		repeat with thisDatabase in theDatabases
			set thisDatabasesResults to lookup records with path thePath in thisDatabase
			set theResults to theResults & thisDatabasesResults
		end repeat
		if theResults = {} then
			display notification "Pfad nicht in offenen Datenbanken enthalten!" with title "Lookup DEVONthink"
			return
		else
			open window for record (item 1 of theResults)
			activate
		end if
		
	on error error_message number error_number
		if the error_number is not -128 then
			display alert "DEVONthink Pro" & space & error_number message error_message as warning
			return
		end if
	end try
end tell

The issue of this way is that the DEVONthink window would be open, but it doesn’t matter in most cases.

Hope it helps!
