'Selection' is understood to be the choosing of one or more objects. 
On the desktop, for instance, one can select the files in a drive 
window with a mouse click, [Shift]-mouse click or by drawing up a 
rubber band box.




Basically the following conventions apply on the desktop:

Mouse click: A single left-click with the mouse selects the object 
clicked on; objects that are already selected must be deselected again 
by this action.

[Shift]-mouse click: This adds the selected object to the set of 
already selected objects (so previously selected objects will remain 
selected). A [Shift]-mouse click on a selected object removes this 
from the set of selected objects again.

Rubber band: By drawing out a rubber band box (left-click at the start 
of the area to be selected and holding the button down drag the mouse 
pointer to the end-point), all objects enclosed by this band will be 
selected; any objects already selected must be deselected again by 
this action. In combination with the [Shift] key the affected objects 
can be added to the set of selected objects.

A very useful type of selection is the so-called realtime selection. 
This describes a procedure under which the selected area is inverted 
already during the movement of the mouse pointer. Many programs such 
as Pure-C, Gemini, Everest or Grismo use this method of selection, and 
even scroll the contents of the window automatically when the edge of 
the window is reached.
