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

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.

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.

Insert Name, Value, or Definition of an Object into the Input Bar

  • Insert the name of an object: Activate Tool Move.gif Move Tool and select the object whose name you want to insert into the Input Bar. Then, press F5 on your keyboard.
Note: The name of the object is appended to any expression you typed into the Input Bar before pressing F5.
  • Insert the value of an object: There are two ways of inserting an object’s value (e. g., (1, 3), 3x – 5y = 12) into the Input Bar.
    • Right click (Mac OS: Ctrl-click) on the object and select item Copy to Input Bar.png Copy to Input Bar from the appearing Context Menu.
    • Activate Tool Move.gif Move Tool and select the object whose value you want to insert into the Input Bar. Then, press F4 on your keyboard.
Note: The value of the object is appended to any expression you typed into the Input Bar before pressing F4.
  • 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 Tool Move.gif Move Tool and select the object whose definition you want to insert into the Input Bar. Then, press F3 on your keyboard.
