how to use the + on the numeric keypad for "+p in vim, Mac Os X
It’s Vim, feel free to remap anything to anything you want.

To detect what you numpad + sends to Vim press C-v then + on numpad – you will see something like

^[Ok


^[ is escape, so you may command your Vim

:map "&lt;esc&gt;Ok "+


Now it should work as expected by you.

However, it would be better to do this kind of mappings not in Vim but in your terminal emulator (which you have not mentioned) by two reasons:


In Vim you have to map all possible prefixes explicitly. You can perform :map &lt;esc&gt;Ok + but it won’t affect "&lt;esc&gt;Ok.
Mapping &lt;esc&gt;Ok to something will add a delay in processing single &lt;esc&gt; press (see :h timeoutlen).
