Input Bar and Input Field
In GeoGebra Desktop, the Input Bar is by default located in the bottom of GeoGebra window. You can show it or hide it using the View Menu or can change it's position within the GeoGebra window.
In the GeoGebra Web and Tablet Apps an Input Field is integrated directly into the Algebra View. Therefore, the Input Bar is not displayed by default if the Algebra View is part of the GeoGebra window. However, the Input Bar can be shown using the View Menu, replacing the Input Field. Both, the Input Bar and Input Field are providing the same functionalities in GeoGebra.
Algebraic Input and Commands
The Input Bar allows you to directly create and redefine mathematical objects in the Algebra View by entering or modifying their algebraic representations (e. g., values, coordinates, equations).
f(x) = x^2
gives you the function f in the Algebra View and its function graph in the Graphics View.Additionally, you may input Commands in order to easily create new or work with existing objects. For more information, please see Geometric Objects and General Objects.
A=(1,1)
and hitting the Enter key creates a free point A with coordinates (1, 1). Create another free point B=(3,4)
in the same way. Then, type in Line[A, B]
in order to create a dependent line through both points A and B.
You can toggle the focus between the Input Bar and the Graphics View at any time by pressing the Enter key. This allows you to enter expressions and commands into the Input Bar without having to click on it with the mouse first.
Displaying Input 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. Hit the Enter key in order to transfer the selected prior input back into the Input Bar.
Insert Name, Value, or Definition of an Object into the Input Bar
Insert the name of an object: Activate the Move Tool and select the object whose name you want to insert into the Input Bar. Then, press F5 on your keyboard.
Insert the value of an object: To insert an object’s value (e. g., coordinates of a point (1, 3)
, equation 3x – 5y = 12
) into the Input Bar, select the Move Tool and click on the object whose value you want to insert into the Input Bar. Then, press F4 on your keyboard.
Insert the definition of an object: There are two ways of inserting an object’s definition (e. g., A = (4, 2)
, c = Circle[A, B]
) into the Input Bar.
- Alt + click on the object to insert the object’s definition and delete whatever input might have been in the Input Bar before.
- Activate the Move Tool and select the object whose definition you want to insert into the Input Bar. Then, press F3 on your keyboard.
