ITERM
A BETTER TERMINAL
EMULATOR

A BETTER TERMINAL EMULATOR: ITERM
WHY?
▸ A lot of features
▸ Split panes
▸ Search
▸ Autocomplete
▸ Paste history

KILLER FEATURES (FOR ME)
▸ Hotkey window
▸ Terminal is never missing, always one click away
▸ My choice is [Alt + >/<]
▸ Instant replay
▸ Get back the small amount of data you just lost
▸ Move back in time: [Alt + Cmd + B]
▸ Move forward in time: [Alt + Cmd + F]
▸ Conﬁguration
▸ Map anything to any key easily
▸ You should map at least numpad number keys and Alt + arrows
▸ ⎇→ = Esc + f and ⎇← = Esc + b

HOW?
▸ It’s free
▸ https://www.iterm2.com/downloads.html

ALTERNATIVE TO BASH: ZSH
WHY?
▸ Better autocomplete
▸ Cycling trough options
▸ Path expansion
▸ Git autocomplete
▸ Right prompt
▸ History search with arrows (eg. git ⇧)

… AND MUCH MORE
▸ osx / Finder plugin (cdf)
▸ Path replacement
▸ Sufﬁx aliases

HOW?
▸ Free of charge
▸ Install oh-my-zsh

oh-my-zsh/master/tools/install.sh)"
▸ http://ohmyz.sh/

MANAGE YOUR WINDOWS WITH SPECTACLE
WHY?
▸ OS X seems to lack proper windows control
▸ Spectacle does one thing and does it right
▸ [Alt + Cmd + F] - fullscreen
▸ [Alt + Cmd + / ] - left/right side of screen (repeat for sizing)
▸ [Alt + Cmd + ⇧/ ] - top/bottom of screen (repeat for sizing)
▸ [Ctrl + Cmd + / ] - high quarters
▸ [Shift + Ctrl + Cmd + / ] - low quarters
▸ [Ctrl + Alt + Cmd + / ] - move window between screens

ARE YOU SERIOUS?
▸ These shortcuts might seem a bit hard but I’m 100% sure
you can learn them with a little bit of practise

HOW?
▸ Free of charge

▸ Note: Disable [Ctrl + C] for centering, if you use Alfred’s
clipboard for that
