In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So ⌘ + D does not mean hold shift. ⌘ + Shift + D does of course.

Tabs and Windows

Function	Shortcut
New Tab	⌘ + T
Close Tab or Window	⌘ + W (same as many mac apps)
Go to Tab	⌘ + Number Key (ie: ⌘2 is 2nd tab)
Go to Split Pane by Direction	⌘ + Option + Arrow Key

Make Your Views Fast by Evadne Wu

• rendering pipeline

• layer tree(your code) vs presentation tree => pass to render tree

• blending vs compositing

view 疊太深 => draw into your own buffer <=> against animation
