You can use the common Windows keyboard shortcuts in the EFT Server administration interface (e.g., CTRL+C to copy, CTRL+V to paste, ALT+underlined letter in menu to open the menu). Microsoft Knowledge Base article #126449, http://support.microsoft.com/kb/126449, describes each of the keyboard shortcuts that are available in Windows.
As in any Windows-compatible application, a button or menu text with an underlined letter has a shortcut key associated with that letter.
In addition to the standard Windows keyboard shortcuts, there are several keyboard shortcuts available in the administration interface. Refer to Main Menu and Toolbar for a table of shortcuts.
