search command history keymap

Fixes: #884
Neovim requires an external tool for proper system clipboard integration.
Some systems install this already by default:
- on Fedora xsel is already installed by default
- on Windows using the choko install the win32yank is alredy installed
This is not installed by default on ubuntu or debian so adding that
to the dependencies list and to the install instructions snippets.
