Notes on command-line utility "screen"

# Put this in ~/.screenrc:
# This will remap CTRL-A (the normal screen command-mode toggle key combo) to CTRL-Z,
#  because I like to preserve CTRL-A to go to the beginning of the command line.

### BEGIN NOTES ON HOW TO USE "SCREEN" ####
# To remap the CTRL-z to CTRL-z. (So that you can use CTRL-A to go to the beginning of the line.)
screen -e^Zz

# From now on, I will use "CTRL-z" for the first  because that's what I remapped the base screen command (CTRL-a by default) to when typing in the "-e^Zz" option above.   The reason I remapped it is because CTRL-a usually brings the cursor to the beginning of the line in bash.  I use that a lot when working at the command line, so I want to preserve that bash mapping.

# To create a new screen buffer:
CTRL-z CTRL-c

# When logging in again, and reusing your previous screen session
screen -rd

# To kill a buffer
exit

# To move to a different screen buffer, say, 42
CTRL-z 42

# To toggle to the previous buffer
CTRL-z CTRL-a 

# View a list of screen sessions
screen -list

# Create a named screen session called "work"
screen -S work

# Resume a named screen session called "work"
screen -r work

# Resume a named screen session called "work" in yet another terminal
screen -x -r work

# To scroll up, first go into "copy mode."  To get into copy mode:
CTRL-z [

# In copy mode, to scroll up, use the vi navigation commands or arrow keys.
CTRL-B to go up one page
CTRL-F to go down one page

# To exist "copy mode":
ESC

# Name your window buffer
CTRL-z SHIFT-a
