Marcus Jaschen 76a2202a20 The slash key is a well-known shortcut to open and focus the
search field in web apps, e. g. DuckDuckGo or Google Plus.

Some editors and pagers use the same shortcut (Vim, less, ...).

This commit adds an event handler for the pressed / key which
calls the `ShowSearch()` function.
