I'm a vim user but in the shell I use Ctrl-a and Ctrl-e to get to the beginning and end. If I need more editing I use Ctrl-x Ctrl-e to hop into vim.

It really shines for navigating history. <esc>/ searches history the same way as the editor search function

You mean, like the “home” and “end” buttons?

C-a and C-e are your friend.
