I can see that Ctrl+left/right jumps to the beginning/end of line. How to change this to Cmd+left/right arrow?

To jump between words and start/end of lines in iTerm2 pick one of the two solutions below.

1. Simple solution (recommended)

1. Open Preferences
2. Click “Profile” tab
3. Select a profile in the list on the left (eg “Default”)
4. Click “Keys” tab
5. Click “Key Mappings” tab (if it exists)
6. Click the “Presets” dropdown and select “Natural Text Editing”

Note: if you have several profiles (f.e. Default and Hotkey Window) and want the same modification to be applied for all profiles, use these steps instead:

2. Click “Keys” tab
3. Choose “Key Bindings”

2. Mapping keys manually (Advanced)

If you don’t want to use the “Natural Text Editing” preset mentioned above, you can map the keys you need manually:

1. Open Preferences
2. Click “Profile” tab
3. Select a profile in the list on the left (eg “Default”)
4. Click “Keys” tab
5. Click “Key Mappings” tab (if it exists)
6. Click the [+] icon
7. Add the shortcuts from the table below

Note

If keyboard bindings already exists for the shortcuts above, they must be removed for the new ones to take effect.
