# Command line
In IDA, the command-line input field is located at the bottom of the **Output window**, just above the status bar. It can be used to enter various commands. By default, it accepts IDC and Python commands (if the Python installation has been found), but plugins may register themselves as command language providers. 
Currently, the following command line providers exist:
* [IDC](/8.5/developer-guide/idc/core-concepts.md)
* [Python](https://python.docs.hex-rays.com/)
* Bochs debugger
* WinDbg debugger
* GDB debugger
When these plugins are active, they will process the entered commands. The current command language can be changed by clicking the button to the left of the input field. The current language can be set as default by choosing "Default CLI" from the context menu of the command line.
The command-line input field can be activated by pressing ., while Esc switches back to the previous window.
