Ctrl+C and Ctrl+V Runs JChem for Office Copy/Paste
Use this option to specify whether JChem for Excel handles Ctrl+C and Ctrl+V events or not. You can easily copy-and-paste structures between MS Office applications when JChem for Excel handles the keyboard events.
The available values for this option are as follows:
The default value is TRUE.
When the value is set to TRUE, pasted textual structure formats are automatically recognized as structures. When the value is set to FALSE, the text is pasted into Excel without converting it to a structure.
