One comment from an experienced user:

"The menus in INX just get in the way!"

Actually, he's right - but only if you already know a good set of commands, and what their
options are. The target audience for INX emphatically does not know such things...

Nevertheless, at some point you will tire of choosing numbers and letters, and want to do
things yourself. This is exactly the aim of INX, in fact - and you can of course turn off
all the pretty colour menus to get a command prompt, simply by hitting X, from most menus..

The problem, if it *is* a problem, is that virtually all GNU/Linux programs (commands)
have a bewildering number of options - and most programs do things in ways that are
"Almost, but not quite, entirely unlike..." 

The reason for questioning whether it is a problem harks back to a comment in an earlier
tutorial, regarding the issue of who supplies the intelligence when using a computer.
Operating systems and applications these days try very hard to make you believe that you
don't need to learn anything to use them. This is a fraud, albeit (in some cases) 
a generous-spirited one.

If you have followed these tutorials in order, you already know more than most computer
users, about what is actually happening under the surface.

O.K. - so what does INX do when you choose a number? It runs commands, of course. So let's look
at some more, and do it ourselves.

If you tried the Radio menu, you saw the actual addresses from which the stream came. Mplayer
was told to shut up and just play - and mplayer likes to be verbose. Try this - you might remember
that the controls for the basic radio menu included "/" "*" "space" "p" and "q" for quit...

Those happen to be mplayer control keys. By now I expect you to know how to return to the tutorial,
so I won't repeat it yet again ;-)

So type
EOHANDHOLDING
echo ; yellow
echo "mplayer mms://abs.egihosting.com/southjz32"

/bin/bash

cat <<EOMPLAYER

Different, isn't it? Most of that stuff mplayer spits out is irrelevant - unless you 
happen to have some of the things to which it refers, or need to track down a problem. 
In those cases, the verbosity is very useful. The mplayer man page, by the way, 
is very thorough, but pretty intimidating!

Will run the slideshow, with automatic size adjustment, and a time interval of 2 seconds.
The -noverbose option turns off the file information at the bottom. 

Of course, you can do this with any directory containing, for 
example, .png and .jpg images. Instead of * you could use for example *.png to show only
.png files, and so on. 

For more info, type "fbi -help" or "cmatrix -help"

Here's a trick for the elinks browser. If you type a series of URLs, they will open in
tabs. You can shift from one tab to another with < and > . To scroll horizontally use [ and ]

Try typing this, and using the search function ( / ) to navigate. You might want to read the 
tips in the "Net & Web" menu about using elinks with Internet radio streams, if you haven't 
already.

cat <<EOMUSIC

The "MOC" ( Music On Console ) player is rather nice. You might have used it already.
The USB access menu is set up so that if you have music on a USB device, you can access
it directly with mocp after it is mounted. See the USB menu. ( mocp is the command to start
MOC - notice that you can quit MOC with q and it will continue to play. If you restart the 
interface, the existing state will be shown. You can stop it with "s").

The above USB hint kind of contradicts the Declaration of Independence, doesn't it?

OK. When you plug in your USB, run the following commands, with appropriate substitution...

If you were expecting hints about the "sc" spreadsheet... sorry, I have a serious mental
block about spreadsheets. I really do. I don't even understand the help.

The "calcurse" calendar looks pretty - but I prefer to make lists and use cal and grep. People
got by rather well with diaries, quills, and similar technology for centuries, too...

You know what a food processor does to food, right? Well, there are these things called
"word processors"... You won't find one in INX.

"wcalc", on the other hand, seems like a nice command line calculator without pretensions,
but with plenty of options.
