An iTerm2 Cheatsheet

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
