I keep an outline in which I'm slowly building up bits of information about Leo (and Linux, Python, whatever). I wanted to find the table of Leo's hooks today. I didn't want to fish around the various Leo files and web pages trying to find it. Instead, I knew I had it in my outline so I searched using the Nav tab for "hook". It found the headline Table Of Leo's Hooks. This node contains the link:
unl:gnx://LeoDocs.leo#ekr.20050903074833.1
CTRL-clicking on the link opened the LeoDocs.leo outline to the desired node. Beautiful!
I get the target UNL of the node I'm viewing with this code:
"""Copy UNL of current position to clipboard."""
p = c.p
g.app.gui.replaceClipboardWith(p.get_UNL())
Then I paste the UNL into the outline I'm using to capture these bits of information.
