## I3
In [I3](http://i3wm.org/) you want to bind rofi to be launched on key-release. Otherwise it cannot grab the keyboard.
See also the I3 [manual](http://i3wm.org/docs/userguide.html):
Some tools (such as import or xdotool) might be unable to run upon a KeyPress event, because the keyboard/pointer is
still grabbed. For these situations, the --release flag can be used, which will execute the command after the keys have
been released.
