Shortcut for "Sync Grids"?

Thanks, something like this works perfectly!

if [ $(defaults read com.binaryage.TotalSpaces2 lockGridsTogether) -eq 0 ]
then
  defaults write com.binaryage.TotalSpaces2 lockGridsTogether 1
  osascript -e 'display notification "Grids are locked together." with title "TotalSpaces Locking"'
else
  defaults write com.binaryage.TotalSpaces2 lockGridsTogether 0
  osascript -e 'display notification "Grids are unlocked." with title "TotalSpaces Locking"'
