How to get Cmd-left/right working with iTerm2 and Vim (without requiring .vimrc changes)?
I want to be able to use Option-left and Option-right to skip words (and Cmd-left/right to go to beginning and end of lines) within Vim as it does at my shell prompt. My Iterm2 preferences have mappings to do this (e.g. Option-left to Esc-H and a one for option-right to Esc-F to skip over words), and this works in the shell locally or when ssh'd to a remote server.
When I use Vim locally or remotely, option-left works, but option-right does not. I suspect this is because Vim naturally listens for Esc-H, but not Esc-F. I am able to get around this by modifying .vimrc file to Esc-b to b and Esc-f to f, but I don't want to do this to every server I'm connecting to.
Similarly, I have the same desired setup for Cmd-left/right for going to beginning and end of a line. I can get this working in the shell via Iterm2 mappings (e.g. Cmd-left to Esc-[h), but Vim doesn't respond at all to this unless I map keys again (e.g. Esc-[h to ^).
Update: I just figured out how to get option-left/right working. I changed mapping in iTerm2 for these to be escape-[1;5D and escape-[1;5C respectively. I still want to solve the Cmd-left/right problem though (I changed my question's title to reflect this). Any ideas?
Answer
To mimic OS X's behavior of sending Cmd-left/right to the beginning/end of a line, I add the following mappings in iTerm2:
Cmd-leftto escape-sequence[1~Cmd-rightto escape-sequence[4~
To mimic OS X's behavior of sending Option-left/right to the previous/next word, I add the following mappings in iTerm2:
Option-leftto escape-sequence[1;5DOption-rightto escape-sequence[1;5C
Special thanks to this blog post for tracking down what I was missing with the cmd-left/right mappings
