I stumbled across the CMD-D hot key which splits the Terminal into 2 panes. But I can't find documentation anywhere on how to close the new pane or even switch the focus to it so I can use it. What are the other commands?
In the most current version of Iterm2, navigate to
Preferences > Profiles > Keys.
+ sign and add new key shortcut. Then scroll to the bottom and select
Send Escape Sequence. Do this twice and after you select escape sequence simply put a
b in the text box for left and an
f for right.
