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.
The links were silently dropped with commit
4c0d975532 "Make clickable icons"
without any mention in the commit message.
Based on the commit title, I would assume this is an additional
functionality and not something that replaces existing stuff.
It's annoying to move the mouse across the screen (reading text from
the left to right) to get to the mark read icon for marking an article
as read.
All changes related to the removal of the links are reverted by keeping
the clickable icons.
