In Vim you can use :cd to change directory across your Vim session. But did you know you can use lcd to change directory for the current window?

I find this useful if I’m in one project and need to dig into some code from another. I will open a new tab and then lcd into place. Once I’m done I can then delete that tab and in my other window(s) I’m still in the directory I was earlier.

See :help lcd for more.
