## How can I select and copy text in a Textual app?
Running a Textual app puts your terminal in to *application mode* which disables clicking and dragging to select text.
Most terminal emulators offer a modifier key which you can hold while you click and drag to restore the behavior you
may expect from the command line. The exact modifier key depends on the terminal and platform you are running on.
- **iTerm** Hold the OPTION key.
- **Gnome Terminal** Hold the SHIFT key.
- **Windows Terminal** Hold the SHIFT key.
Refer to the documentation for your terminal emulator, if it is not listed above.
