Hide debug window on process termination	Automatically hide the Debug tool window when the debugged program terminates.
Scroll execution point to center	If this checkbox is selected, the line with the current execution point will be kept in the middle of the screen.
Click line number to perform run to cursor	If this checkbox is selected, you can click a line number in the editor to run program execution to this line.

Built-in server

Item	Description
Port	Use this spin box to specify the port on which the built-in web server runs. By default this port is set to 63342 through which PyCharm accepts connections from services. You can set the port number to any other value starting with 1024 and higher.
Can accept external connections	If this checkbox is selected, then the files on the built-in server running on the specified port are accessible from another computer. If this checkbox is cleared (by default), then the debugger listens only to local connections.
Allow unsigned requests	For security reasons, any request to a page on the built-in server from outside PyCharm is by default rejected and the authorization popup is displayed. To access the requested page, click Copy authorization URL to clipboard and paste the generated token in the address bar of the browser. However this behavior may be annoying, for example, it may block your debugging session if manual intervention is impossible. To suppress displaying the authorization popup, select the Allow unsigned requests checkbox.
