Sending commands to all iTerm2 panes
I use iTerm2 as a my termimal of choice on my mac (along with oh-my-zsh).
There are times when I have multiple iTerm2 panes on one window and I want to send commands to all of them. This is especially useful when updating npm packages across several apps, especially if you have a microservice architecture.
To do this on a Mac, the shortcut is
cmd + shift + I
If you want to get out of this state (this is something that was hard to find online), the shortcut is
cmd + opt + shift + I
