### 2.15 The Shell and Python Windows

These windows give access to the various scripting languages supported by GPS, and allow you to type commands such as editing a file or compiling without using the menu items or the mouse.

An OS shell window is now also available in GPS, providing a simple access to the underlying OS shell as defined by the `SHELL` or `COMSPEC` environment variables.

To show the shell consoles, select the menu `Tools->Consoles`.

See Scripting GPS for more information on using scripting languages within GPS.

You can use the <up> and <down> keys to navigate through the history of commands.
