Hey Duncan,
If you want to get the Unix path of a file/folder into the clipboard in Path Finder, all you have to do is Copy (Cmd-C).
If you want to use those paths in a macro then it's faster to get them with AppleScript.
------------------------------------------------------------
# Get Posix Paths of Selected Items in Path Finder
# Assign a Keyboard Maestro variable to the value.
------------------------------------------------------------
set pfSelList to missing value
tell application "Path Finder"
set pfSelList to selection
if pfSelList ≠ {} then
repeat with i in pfSelList
set (contents of i) to POSIX path of (contents of i)
end repeat
end if
end tell
if pfSelList ≠ missing value then
set AppleScript's text item delimiters to linefeed
set pfSelList to pfSelList as text
tell application "Keyboard Maestro Engine"
try
set value of variable "myVariableName" to pfSelList
on error
make new variable with properties {name:"myVariableName", value:pfSelList}
end try
end tell
end if
------------------------------------------------------------
