Create your ssh key to talk to github without username and password prompts.
ssh-keygen -t rsa -b 4096 -C [email protected]

# > hit enter to have no password
Configure your username and email settings 1 time
git config --global user.name "Michael Smith"
git config --global user.email [email protected]
Go to github.com/settings/ssh to add your new ssh key to github.
From your server copy the contents of ~/.ssh/id_rsa.pub and add it to the github key.
Name it after your development environment.
Get this repo, and load it to your environment so all the helper scripts and commands are available.
Specifically ./profile.
git clone [email protected]:smith11235/dotfiles.git
cd dotfiles
ruby dotfiles.rb

Either detach and exit, or just close your terminal window.
Detaching lets you return to your work later as if you never left.
ctrl-b d # detatch from session

For any ruby/rails project, from your root directory make and use a project specific rvm/ruby install.
cd my_project
tn my_project # new tmux session in this directory
which rvm # ensure none is found
which rails # ensure none is found
build_rvm # build rvm, install Gemfile tat my_project # attach to tmux session where you left off
ctrl-b c # new tab for work
load_rvm # load rvm environment

To edit code on a server, without a mouse
vim some/file.txt
By default you are in command mode and cannot edit the file.
In general most 'commands' will start by typeing :.
i # enter insert mode before the cursor
... edit text with your keyboard...
esc # exit insert mode, back to command mode
Other ways to enter insert mode:
shift+i # start editing at beginning of line
a # start editing after the cursor
shift+a # start editing at end of line
o # start editing a new line below the cursor
shift+o # start editing a new line above the cursor
j # down
k # up
h # left
l # right
w # word forward
b # word back
All of these are from command mode
# open a new file in a tab
:tabe path/to/file.txt
# save your edits
:w
# close a file/tab
:q
# switch tabs
ctrl+h # tab left (h is the move left key!)
ctrl+l # tab right (l is the move right key!)

This is based on regex's, they are worth learning.

v # start a basic selection, use movement keys to select text
shift+v # start a full line selection, use up/down movement keys to select more lines
ctrl+shift+v # start a column/section selection, movement keys to select text
