Revit Shortcut Highway is an application that allows one to manipulate keyboard shortcuts for AutoDesk Revit 5.1 commands.
Prior to the release of this application, the only means available to perform the operation of manipulating command shortcuts was by manually editing the Keyboardshortcuts.txt file (residing in the AutoDesk Revit 5.1 installation folder) via a text editor.
