Terminal
The linux terminal is your lifeblood. There are so many - TOO MANY - options. I'll gather a few of my favorite things here.
screen keyboard copy from buffer
HOW DID I LIVE SO LONG WITHOUT THIS!
- Ctrl-A-esc to get into buffer navigation mode
- space to mark the start of the copy buffer (non-column)
- space to mark the end of the copy buffer
- then you can use Ctrl-A-] to paste - wait, wut? useless... what about X buffer?
- add this to "your screen .rc file" to send buffer to X clipboard too!
bindkey -m ' ' eval 'stuff \040' 'writebuf' 'exec sh -c "/usr/bin/pbcopy < /tmp/screen-exchange"'
