There's a non-programming way to do this as well. If MicroStation's Input Focus is "Home" hitting the Enter key will activate the Key-in Window. A new Key-in window will appear with the active cursor or if the Key-in window is docked the active cursor will be in the docked Key-in window.
Either the ESC key sets MicroStation to Home or the out of the box Function key F12 or the command "inputmanager home"
There's an icon in the lower left of the Status bar that shows which "focus" is active, just hover over the icons and a tool tip will describe each one. When MicroStation's Input Focus is Home the icon is a House.
Search in MicroStation's Help using "focus", it will describe how it works.
