[Rd] Double-clicking in tk list dialogs

[Prof Brian Ripley]

It does not seem to be standard practice for Tk-based interfaces (and 
indeed it was not part of GraphApp on Windows -- I added it after some 
years).

If you supply a tested patch to the R-devel sources it will be considered 
for 2.8.0.  The 'next version' is 2.7.2 and imminent, so I don't think we 
would consider it for that unless you get lots of support in the next 24 
hours.

I am surprised you have not set up a preferred CRAN mirror long ago.
