One additional thing, that I should have included here, that also, makes 
that last part above, simpler, is that I also keep a number of separate 
terminal windows open; one for each application, which means that I need 
only use one or two key presses of the up arrow, to re-invoke  a 
command; so that I have one terminal window for alpine, one for system 
commands, like the system update combination command, one for youtube-dl 
(for each path to which I download videos; one for videos from 
television stations, one for cooking videos, one for genealogy videos, 
etc, etc,etc, each of which, is downloaded into a separate pathway), 
and, apart from when a system reboot is required, such as when a kernel 
upgrade is performed, usually, only one up arrow key press is required, 
to re-invoke the applicable command.
