This is because it's only been around for a very short while. I can
document it, but the discussion about the merits of the feature is
still ongoing and new viewpoints are still coming (and I haven't
pushed the default keyboard binding yet).
In the meantime, the docstring should be enough to actually use it,
since it's really quite simple:
def actOnNode(self, event):
""" Execute node-specific action (typically defined by plugins)
Actual behaviour is to be defined by plugins.
Here's how to define actions for nodes in your plugins::
import leo.core.leoPlugins
def act_print_upcase(c,p,event):
if not p.h.startswith('@up'):
raise leo.core.leoPlugins.TryNext
p.h = p.h.upper()
g.act_on_node.add(act_print_upcase)
This will upcase the headline when it starts with @up.
