General program information
Name 	This is the name of your program as it appears in the Main menu. It can be different from the real executable name. For instance the name of mc executable is "Midnight Commander".
Comment 	Describe the program in greater detail in this field. This is entirely optional.
Command 	This is the name of the executable program. Make sure that you have permission to run the program.
Type 	This field is similar to the Comment field. Describe the type of your program here.
Work Path 	Specify the work path of the program. This will be the current path when the program launches. It does not need to be the same as the executable location.
Icon List 	 Click this icon to display a choice of icons. Choose an icon for your program.
Run in Terminal 	You must check this if your program requires terminal emulator in order to run. This mainly applies to console applications.
Terminal Options 	Put all terminal options in this field.
Run as different user 	If you want to run this program as a different user (not you), check this checkbox, and provide the username in the Username field.
You can assign a special keyboard shortcut to launch your program.
Click the empty button to the right of the Current key checkbox and press the key combination on your keyboard that you want to be assigned to your program.
A dialog box will pop up, allowing you to assign a second keybinding to the same item by checking the Alternate button. This might be useful, for example, if you often switch keyboard maps, and some shortcuts are not as convenient to type at all times.
Click the x to clear the shortcut, if you made a mistake. Check the Multi-Key box if you want to assign a shortcut that uses more than one key.
By default the Auto-Close box is checked, and the dialog will close when you have selected a keybinding. Uncheck it if you want the dialog to stay open.
