+### SSH Remote Control
+
+You can enter a SSH session with your networked Raspberry Pi, launch the ofxPiMapper executable and access all the functionality by using the keyboard. Use the same commands listed in the above table, use `/` as the replacement for the `SHIFT` key as it is not that easy to capture `SHIFT` keypress when on SSH. The `/` works as a toggle, you have to press it once to simulate `SHIFT_DOWN` and one more time to simulate `SHIFT_UP`. It is particularly important when moving surfaces and vertices over long distances. The `/` key enables 10px steps when pressing arrow buttons.
