Select mode is used to choose notes and elements. After selecting an element, you can move, edit, copy or delete it. "Select mode" allows you to select elements specifically to edit them. One essential tool for this purpose is the "Properties window", which will open when you start FORTE. Access and edit numerous functions and commands related to the selected element.
Should the "Properties window" not be open by default, click the "Properties" icon in the "Palettes" group to open it with a few clicks.
