Commands
GeoGebra offers algebraic input and commands in addition to the Graphics Tools. Every Tool has a matching Command and therefore, could be applied without using the mouse.
Note: GeoGebra offers more Commands than Graphics Tools. Therefore, not every Command has a corresponding Graphics Tool!
Commands can be typed into the Input Bar. They are followed by a set of parentheses (or brackets) containing the parameters necessary for the command.
Example: The command creates a polygon using the existing points A, B, and C.
Hint: If you need further information about a certain command, here you can find a full list of commands and also CAS specific commands.
Automatic completion of commands
After typing the first three letters of a command into the Input Bar, GeoGebra tries to complete the command and shows you the required parameters within parentheses or brackets.
- If GeoGebra suggests the desired command, hit the Enter key in order to place the cursor within the parentheses or brackets.
- If the suggested command is not the one you wanted to enter, just keep typing until the suggestion matches.
