I had to use the latest master commit (v1.9.3-99-g240d8a0e) for this to
work since apparently there is a bug in v.1.9.3 that ignores the binding
of ESC.
f should filter and not find. All filters should be cleaned when
changing directories.
C-t should open a new tab like it does in almost every GUI application.
Apparently there is a bug in my st setup that leads to the window title
being changed independently of tmux running.
Since my i3 setup checks for the window name for the scratchpad terminal
this has to stop.
