log() FIXME: seems to bring up a dialog allowing the user to enter a message which will get written to the debug log; useful to mark a position in the log
menu(fromosd, href, replace) Brings up the menu (may be used as ). First optional argument, fromosd, is to be specified as 1 when calling this command from an osd button by the tap or mouse click, otherwise it may be omitted or set to zero. You may get directly into the sub-menu by specifying its href anchor like this:"#Actions") . Also, if href is specified, this command may close currently opened sub-menu and open another one on its place if 'replace' is non-zero"#Actions",1).
osd_set_attr(name, attr, value) Sets the attribute of an OSD item. The OSD item must have a name attribute matching the name parameter in the call. attr is the name of the attribute, and value is the new value.
pois(position,filter,isaddressfilter) Displays POIs around given point, possibly filtering them by text string as it would be entered in POI filtering dialog. Second and third arguments may be omitted.
position(position, text, flags) Presents possible operations on a position (set as current location, set as destination etc.). position is a coordinate-type attribute (e.g. position_coord_geo).
quit() Closes Navit.

Use as gui.spawn() when calling from an OSD item.
FIXME: is the number of parameters fixed or variable? Limitations?
