I wanted to know how I could map the escape key to the right "alt" key on the mac keyboard ? Is that possible ?

    I don't think so. I'm pretty sure that Vim can't tell between left and right alt, and even if it could I don't think you can map things just to alt. You need it to be alt + another key.

    I second @Tumbler41: vim can't make a difference between right and left alt keys and I think I've seen other question about mapping something to alt only and if I remember well the answer were to make the terminal do that.

  • It's not vim-specific but you can have a look at pqrs.org/osx/karabiner/seil.html.en, it's useful for remapping specific keys. e.g. remapping caps lock with <esc> or <ctrl>

For the Mac (pre Sierra) you can install Karabiner which lets you do that and more.

Look for Option_R to Escape.

If you already have Sierra you need to wait for the Karabiner update.
