### 4.1.2. Animation

To change a number or angle continuously select Move mode. Then, click on the number or angle and press the + or – key.

Keeping one of these keys pressed allows you to produce animations.

Example: If a point’s coordinates depend on a number k like in P = (2 k, k), the point will move along a straight line when k is changed continuously.

With the arrow keys you can move any free object in Move mode (see Animation; see mode Move).

Note: You can adjust the increment using the Properties dialog of this object.

Shortcuts:

· Ctrl + arrow key gives you a step width of 10 units

· Alt + arrow key gives you a step width of 100 units

Note: A point on a line can also be moved along its line using the + or – key (see Animation).
