Select
With this mode you can select elements with the mouse.
You can easily recognize selected elements, since they
are highlighted in all views. There are three reasons why you
might want to select elements:
-
The most common use of the select mode is individualizing the
appearance of geometric elements. All changes that you make
in the Appearance Editor
are immediately applied to all selected elements. If for
instance several lines are selected and you move the size
slider in the the Appearance Editor, then the thickness of the
selected lines changes.
-
Selected elements may be deleted by using the "Delete" action.
-
Elements may be selected to define "Input", "Output" and
"Hints" for an exercise. For details on this consult the
section about creating interactive web
pages and exercises.
You can select elements in the view either by clicking over them or by
dragging the mouse with left button pressed. Depending on what
you do, four different behaviors are possible:
-
When you click with the mouse somewhere on a view, then
exactly those elements hit by the mouse pointer will become
selected. All other elements will be deselected.
-
When you keep the shift-key down while clicking the mouse over
an element then the selection state of the element will
toggle. The selection state of the elements not hit by the
mouse will stay the same. You can use "shift-clicking" to
select many objects.
-
When you drag the mouse while holding the left button down,
then those elements that you touch while you move will become
selected.
-
When you drag the mouse while holding the shift-key and the
left button down, then those elements that you touch while you
move will be deselected.
We strongly recommend playing with the different possibilities of
the select mode.
