[WriteLog] RITTY Edit Menu in WriteLog - what does it do?

[Jim Smith]

Getting ready for NAQP RTTY.  I use RITTY for my main Rx TNC.  At the 
top left corner of the little RITTY window in WL there is an icon which 
looks like a green tree.  If you right click on it you get the usual 
Move, Size, Close, etc. choices.  You also get an Edit choice.  It has 4 
options,  Mark, Copy Enter, Paste, and Scroll.  I could find nothing in 
the RITTY manual about these.  Can anyone help me find out what these do?
