When Bokeh tools are available, one is always selected by default (normally "pan"). Is there a way to have all tools be deselected while still making them available? This way the reader is less likely to mess up the plot by accident, especially on a small mobile device.

As of Bokeh 0.12 or so, it is possible to configure which tools are active:
# configure so that no drag tools are active
plot.toolbar.active_drag = None
# configure so that Bokeh chooses what (if any) scroll tool is active
plot.toolbar.active_scroll = "auto"
# configure so that a specific PolySelect tap tool is active
plot.toolbar.active_tap = poly_select
# configure so that a sequence of specific inspect tools are active
# note: this only works for inspect tools
plot.toolbar.active_inspect = [hover_tool, crosshair_tool]
