Is there a way to temporarily expand a split pane into full tab and go back again when done? I am looking for a keyboard shortcut to do so. The use case is to be able to temporarily switch to full-screen on demand.

8@rizidoro is right! Cmd+Shift+Enter = temp fullscreen – Serge Velikan Oct 08 '13 at 11:06

1Life-changer. Also good to know: Cmd+Enter toggles window fullscreen – Landon Kuhn Sep 29 '17 at 20:02

To maximize your active panel, just Cmd + Shift + Enter on the screen you want to expand.

9@Alper Go to Preferences > Keys > Action > Select Menu Item > View > Maximize Active Pane and enter a custom shortcut. – Qaz Dec 14 '17 at 00:13

13Maybe things have changed. iTerm2 - 3.2.8 I had to the following for customization Preferences > Keys > '+' (to add a new action) > Under Action select 'Select Menu Item' > Under view you should see 'Maximize active pane' .. So basically "Select Menu item" is the Menu items displayed for iTerm and you can customize any of those . – Ashwin Apr 15 '19 at 10:37

You can maximise and minimise your current panel by using Cmd + Shift + Enter
There are a lot of hot keys to remember and when starting out it can be helpful to print out a cheat sheet or to scan the documentation with find
in your browser.

For me, I cannot find menu section Preferences > Keys > Action > Select Menu Item > View > Maximize Active Pane
My workaround is right clicking on the pane, and select Move Session to Window
and maximize that window.
We can then Move Session to Pane
to move it back.

1Its not that easy to find. `Select Menu Item` is an entry in the combobox which reveals an additional combobox on activation. – ManuelSchneid3r Mar 26 '19 at 16:56

1The menu section is different in iTerm2 as of April 2022. An up-to-date answer is in comment https://stackoverflow.com/questions/13243933/iterm2-how-to-expand-split-pane-temporarily#comment98057836_16483592. – miguno Apr 06 '22 at 10:18

The easiest way is to double click on the panel title, it will expand. Double click again to reduce it
