Oficina (Portuguese for Workshop) or the Paint Activity recently started
using the slider to adjust the pen line, brush stroke, eraser  size:
(
http://git.sugarlabs.org/projects/paint/repos/mainline/blobs/master/OficinaActivity.py#line136
)

def key_press(self, widget, event):
    sliders = {65474: -5, 65475: -1, 65476: 1, 65477: 5}
  if event.keyval in sliders:
      self.area.change_line_size(sliders[event.keyval])

But, testing with os852 and Paint 27, showed that f5 (the first slider
button) activated Journal search and  f6  activated the Frame as in the
http://wiki.laptop.org/go/OLPC_English_Non-membrane_Keyboard, and f7 & f8
seemed not to affect the tool line size.
