在OS X终端中搜索的单键快捷方式

Question

One of my favorite options in OS X Terminal is searching through previously typed commands. I use it a lot. What I don't like about it is the shortcut, it's ctrl + R . In modern notebooks, ctrl is not placed to be found immediately. I would love to use single key to start searching, maybe tab on empty prompt could do the trick? It's useless anyway.

I'm using OS X Yosemite.

Simple: You can add the following to your .profile / .bashrc / .bash_profile :

bind [key]:reverse-search-history

For example,

bind '`':reverse-search-history

to bind the backtick key (above Tab on a US keyboard) to the search history function. (Note that shift-backtick to get tilde will still work normally, and you can use $() in virtually every context that normally requires the backtick).
