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.
Batteries are divided in two ways, by application (what they are used for) and construction (how they are built). The major applications are automotive, marine, and deep-cycle. Deep-cycle includes solar electric (PV), backup power, and RV and boat house batteries.
