How to save a text file in Safari ?
Method1: Hold Control button down (Ctrl) and click on a name. You will get a menu. Select " Download Linked File As".
Pick the right directory, click Save. The default folder to save is "Download" or you can change it to "Desktop"
For Mac with 3 button mouse, Right Click on the URL will get the same menu.
Method2: If you click on the file and now the plain text file is displayed in your browser.
File > Save As …. change the drop down menu from "web archive" to "page source".
You will only see the root of the filename in the Export As dialog but it's fine since OSX will add the .txt extention.
Again Save to Desktop or Download as you wish.
