An experimental Leo button which executes the currently selected node as a python script after invoking User Account Control (UAC). Not fully functional yet -- and dangerous.

python script after invoking User Account Control (UAC).

You could easily bork all your data or even your computer with this: it runs
code with admin privileges, no sanity checking, and very limited feedback. By
default tracebacks etc. are silently swallowed. The only feedback you'll get is
what you explicitly add, and only to gui widgets or files on disk at that, as
Windows has probably hidden the console window.

    1. Copy and paste the full text from below into any Leo outline pane 
    2. save and reopen the workbook to create the button 
    3. navigate to a node and push the [run-elevated] button, but for heavens
        sake be careful!
    
Limitations: 
    - if Leo was started with pythonw.exe instead of python.exe there
    is zero feedback for syntax errors etc. 
    - the node script must not have any doublequotes -- "
    - there may be length limitations, likely about 8k characters
