On keyboards without the meta key it is often mapped to the escape key, Esc, such that in order to simulate, say, Meta+S one has to press the Esc key, then release it, and then press the S key. GNU nano can also use pointer devices, such as a mouse, to activate functions that are on the shortcut bar, as well as position the cursor. See also
Deep-cycle batteries used in RVs typically come in 6- or 12-volt configurations. Six-volt batteries must be installed in pairs and wired in series (connected together so that a + terminal is connected to a â on the other side) so that their combined voltage will be a nominal 12.
The basic RV charging system is called a Converter-Charger. Its primary function is to convert 120v shore power to 12V DC power so that your battery does not need to provide DC while you are plugged in. Its secondary function is to charge the battery(s) when and if it has excess capacity.
