This panel shows key mappings. You can double-click on a mapping to edit it. When the "Keyboard Shortcut" field has focus, you should press the keystroke that you want to modify (even if it involves modifiers like Cmd). The following actions are available:
- Ignore - The keypress will do nothing.
- Do not remap modifiers - If modifier remapping is in effect (set under Preferences > Keys), it can be disabled for certain key combinations. When you choose this action, modifier remapping is temporarily disabled so you can press the key combination unremapped in the key field.
- Remap modifiers in iTerm2 only - If modifier remapping is in effect (set under Preferences > Keys), it can be set to not affect other applications that may listen for global hotkeys. When you choose this action, modifier remapping is temporarily disabled so you can press the key combination unremapped in the key field.

- Send ^? / ^H Backspace - Modern systems use ^? for backspace, while some legacy systems use ^H.
- Send Escape Sequence - This action allows you to enter some text that will be sent when the associated key is pressed. First, the ESC character is sent, and then the text you entered is sent. There are no special characters and no escaping is necessary.
- Send Hex Code - This action allows you to enter a sequence of hex codes that will be sent. Each value should begin with "0x" followed by one or two hex digits (0-9, a-f, or A-F). Each code should be separated by a space. You can see a list of hex codes on http://asciitable.com/ in the "Hx" column.
- Send Text - This action allows you to enter a text string that will be sent when the associated key is pressed. The following escape characters are supported: \n (newline), \e (escape), \a (bell), \t (tab).
- Send Text with "vim" Special Characters - This action allows you to enter a text string that will be sent when the associated key is pressed. The following special sequences are supported, where the "." characters are placeholders: ... (three-digit octal number), .. (two-digit octal number; must be followed by non-digit), . (one-digit octal number; must be followed by non-digit), \x.. (two-digit hex number), \x. (one-digit hex number), \u.... (four-digit hex number), \b (backspace), \e (escape), \f (form feed), \n (newline), \r (carriage return), \t (tab), \ (backslash), \" (double quote), \<C-.> (control key), \<M-.> (meta key)

You can add a new keymapping by pressing "+". You can remove an existing mapping by selecting it and pressing "-". Three presets are provided: "Xterm defaults" is the normal key mappings, while "Xterm defaults with numeric keypad" disables the "application keypad" in favor of the numbers and symbols that the numeric keypad typically emits. "Terminal.app Compatibility" tries to emulate the way that Terminal.app sends keys by default.
Delete sends ^H
If you are on a legacy system that does not accept ^? for backspace, select this and it will add a key mapping for you.
Allow Application Keypad Mode
Some full-screen progarms (like emacs) switch the keyboard into application keypad mode, which changes how the numeric keypad behaves. Disabling this option causes iTerm2 to never enter application keypad mode.
Report modifiers using CSI u
Enables a more powerful keyboard reporting algorithm that some applications may use to enable the use of modifiers on more keys and more combinations of modifiers.
Left/Right Option Key Acts As
It is common to use a modifier to send so-called "meta keys". For most users, selecting "+Esc" here is the right choice. The "Meta" option sets the high bit of the input character, and is not compatible with modern systems.
A hotkey opens a dedicated window with this profile
When enabled, a dedicated hotkey window is attached to this profile. The Configure Hotkey Window button lets you configure the hotkey and other attributes of the window. For more information, see Hotkey Windows.
