I am new to Automator and AppleScript. I see a couple of links about customizing the dock, but they seem to be doing more than I need (or understand). Is there a quick, short way to do this ?
You can set the Dock magnification via AppleScript like this:
tell application "System Events"
tell dock preferences
set properties to {magnification:true, magnification size:1.5}
end tell
end tell
