Hello Darrel
If you are in a Linux console, using speakup, then with the numlock OFF,
using these keys on the keypad will let you scroll up and down the screen:
Keypad 7 = scroll up a line
Keypad 9 = scroll down a line
The other numbers on the keyupad do other things, but these are the most
used.
Note, again, this is with numlock OFF.
Numlock is the key in the top left corner of the keypad block on the
right of a standard PC keyboard.
A good tip when listing files is to use the -1 flag to get the files in
a single column:
ls -1
Then you can use keypad 7 to scroll up and read each file name.
I often redirect the output from 'ls -1' like this:
ls -1 > res
Then you can edit the 'res' file to see the list of files:
nano res
Doing this tends to leave a plethora of 'res' files all over though, so
remember to harvest them.
I could give you a recursive find command that would find all the files
of a certain name, top down, and delete them, but find is incredibly
powerful and deleting stuff with it is a bit dangerous.
When you have done scrolling up and down, you can just press return
wherever the browsing cursor is on the screen and you are back at the
prompt.
You could also ad an alias entry to your .bash_aliases file like this:
alias ls1="ls -1"
And then:
source .bash_aliases
Then the command 'ls1' does the same. And you can add other flags to it.

Hi Everyone,
My name is Darrel and I live in the US.
I have dabbled in programming, (coding) on and off my whole life. I currently
write in html, PHP, MySQL and the rest of the web stuff.
I know almost nothing about Linux, other than I prefer it as a web server and
this is mostly how I have interacted with it.
A few years ago I needed to get a couple of measuring devices that had USB
connections to talk to me and I did, with the help of this list and a
Raspberry pi.
So that was the last time I used Linux at the command line level.
So now I would like to get back into it. I want to learn a little python and
think the PI is a good place to play.
Today I rewrote an SD card and with the help of this list I have my PI3B
talking with orca both in the shell and the GUI.
Now, with this background stuff out of the way I have a couple of questions.
Here are the first two.
As a totally blind user who is fluent with windows, and Mac OS and have both,
is the PI the best place to try python. I would like to because it is pure
Linux.
Question 2, When I do anything in terminal like listing the directory, I hear
the results immediately but I can not seam to go back and read the output
again. Is there a way to do this?
Thank You,
Darrel
