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.
A RV battery designed for lower power and deep cycling will last longer and perform better than an engine starting battery. The best deep cycle batteries will last three to four times longer than a starting RV battery under the same conditions. Deep cycle battery capacity is measured in AH (Amp-Hours), meaning the total number of amps of power it can deliver over a 20 hour period.
