Remap modifier keys
iTerm2 allows you to change the meanings of the modifier keys only within iTerm2. This is useful, for example, if you find it difficult to press "option" for "meta" and would prefer to use "command" for that purpose.
To switch tabs
Tabs are normally navigated with cmd+number, but you can change the modifier used for that function here.
To switch windows
Windows are normally navigated with cmd+opt+number, but you can change the modifier used for that function here.
Emulate US Keyboard
If your keyboard layout requires you to hold Shift (or some other modifier) to press a number, enable this to treat the top row of keys as number keys even when Shift is not pressed. This only affects switching panes, tabs, and windows by keyboard as configure in the preceding settings.
Show/Hide iTerm2 all windows with a system-wide hotkey
When enabled, you can focus the Hotkey: field and press a keystroke. From then on, pressing that keystroke (even when iTerm2 is not the front application) will cause iTerm2 to come to the front. If it is the foreground app, it will be sent to the back. This requires that you enable access for assistive devices in the Universal Access panel of System Preferences. For more information, see Hotkey Windows.
Create a Dedicated Hotkey WIndow
Sets up a new hotkey window profile if you don't already have one. For more information, see Hotkey Windows.
Add Touch Bar Item
This button is only visible if your OS version supports touch bars. By pressing this button, you can define a new custom touch bar button with any of the actions you can assign to a key (see below). You can then add the custom button to your touch bar with View > Customize Touch Bar.
Global shortcut keys
This interface works like the keyboard shortcut system in profiles (described above) but it affects all profiles. Settings here are overridden by those in a profile's key mappings.
See the list of key binding actions at Preferences > Profiles > Keys.
