Selection

In Silo's default selection scheme, the left and middle buttons of the mouse are used in combination with keyboard modifiers to perform all selection functions. Generally, left click is used to select visible elements (the front-most ones which can be seen on screen), while middle click is used to select through (elements which can be seen as well as those which are hidden by other elements but fall within the area of selection). Make special note of Tweak listed below, as it is one of the most useful selection tools in Silo.  All mouse controls can be modified in the Mouse Settings and all keyboard shortcuts can be modified in the Keyboard Settings.
