linux surface

Hi,

is it correct, that there is no input devices available for the linux
surface of the netsurf browser? And if yes, is there a way to control
the browser if using the linux surface?
I'm requesting this, since I have the netsurf running with the linux
surface, but can't control it by keyboard or mouse.
As an alternative I try the sdl surface, but it's so much bigger and
I'm looking for a as small as possible browser. OK, if the sdl should
be the only way, since I need to control the netsurf. Is it possible
to compile sdl without all the (for me) unneeded stuff like sound
support?

Best thanks
