For properties files, type in the desired key and value in the edit spaces and select the Insert menu. The information will be inserted in the table above the current selection. For EPS files, type in the desired key and select the Insert menu. The key will be inserted into the table above the current selection with an empty value. Use Change (button/menu) to include the desired value information. As with Change, Insert will save the file with no backup copies.
