File Path shows full path to the file (i.e., file name includign all parent directories, such as /usr/share/doc/file-roller/Copying. Other columns should be self-explanatory.
History Size allows you to specify how many recently accessed files should be shown in File Roller File menu. By default, History Size is set to 5, so 5 most recent files are shown.
To change or add keyborad shortcuts associated with menu items, open the corresponding menu and move the mouse cursor over the menu item for which you want to change the shortcut (do not click on the menu item!). While the mouse cursor is over the desired item, press the key combination you want to use as the shortcut for this item. The menu will change to show the new shotrcut. That's it - now you can use the new shortcut.
