I have a folder open showing many files in the sidebar. Some are CSV files from a spreadsheet. I would like to be able to open the CSV files with the appropriate application (Open Office, in my case). I have found the page where I should be able to say "open this file with appplication " but have not been able to get it to work. Can someone help me to get this working? I’m using ST2 on MacBook OS X 10.8.2.
