Before we get started

These are the keys usually used in combination with normal keys on Mac:

• Command (or Cmd) ⌘
• Shift ⇧ (I will write as shift to avoid confusion with ↑)
• Option (or Alt) ⌥
• Control (or Ctrl) ⌃
• Caps Lock ⇪
• Fn

The guide below assumes that you are using spectacle.

Also, I’m not going to cover really basic ones like ⌘ + F, ⌘ + Q or ⌘ + , (You know what I’m saying).

So.. here are the most useful commands I use on my Mac (to be updated more):

MacOS general

• Make full screen
  • MacOS default: ⌃ + ⌘ + F (Puts up another big ‘desktop’)
  • Spectacle: ⌥ + ⌘ + F (Just fits the maximum size of the screen. Does not put up another big ‘desktop’)
• Emulate force touch: place your mouse on something you want to force touch + ⌃ + ⌘ + D
• Emulate swipe to previous/next display:
  • previous: ⌃ + ←
  • next: ⌃ + →
• Switch to desktop 1, 2
  • go to keyboard -> shortcuts -> mission control, and turn on options for Switch to Desktop 1 and Switch to Desktop 2.
  • Switch to Desktop 1: ⌃ + 1
  • Switch to Desktop 2: ⌃ + 2

• Capture
  • Entire screen: ⌘ + shift + 3
  • Partial screen: ⌘ + shift + 4
  • Partial screen with more guidance (launch screen capture): ⌘ + shift + 5
• Move focus to the menu bar (this one needs configuration because on macs with touch bar, it’d be harder to use the default option):
  • default: ⌃ + F2
  • I changed it to: shift + ⌥ + M
  • or: ⌘ + ? to focus on help first

• Close current window: ⌃ + b, then &
• Next window: ⌃ + b, then n

• Switch to the pane in direction: ⌃ + b, then arrow key
• Resize panes (probably most used): ⌃ (hold down) + b (press), then arrow key note: you have to disable Mission control, Application windows, Move left/right a space on MacOS because they override tmux controls when using this function.
• Copy to clipboard:
  • Go to iterm config
