Input Bar

Input bar is by default located in the bottom of GeoGebra window. You can show it or hide it via View Menu.

It allows you to create and redefine mathematical objects

• directly, using their algebraic representations (e. g., values, coordinates, equations). This representation is shown in the Algebra View. See Geometric Objects and General Objects for details.
• using Commands.

Note: Always press Enter after typing algebraic input into the Input Bar.

Note: Pressing Enter at any time toggles the focus between the Input Bar and the Graphics View. This allows you to enter expressions and commands into the Input Bar without having to click on it with the mouse first.

Example: Typing A=(1,1) creates free point A with coordinates (1,1). Typing A=Midpoint[(2,0),(4,0)] redefines A: it becomes dependent point.

Display Input Bar History

After placing the cursor in the Input Bar you can use the ↑ up and ↓ down arrow keys of your keyboard in order to navigate through prior input step by step.

Note: Click on the little question mark to the left of the Input Bar in order to display the help feature for the Input Bar.
