vim: install vim-sneak

Sneak is invoked with s followed by exactly two characters:

s{char}{char}

    Press sab to move the cursor immediately to the next instance of the text
"ab".
        Additional matches, if any, are highlighted until the cursor is moved.
    Press ; to go to the next match (or s again, if s_next is enabled; see
:help sneak).
    Press 3; to skip to the third match from the current position.
    Press ctrl-o or `` to go back to the starting point.
        This is a built-in Vim motion; Sneak adds to Vim's jumplist only on s
invocation—not repeats—so you can abandon a trail of ; or , by a single ctrl-o
or ``.
    Press s<Enter> at any time to repeat the last Sneak-search.
    Press S to search backwards.
