Thanks to all.
paulsm4, this looks like something that may work if I had 30 years experience with Linux based OSs instead of 5 or 6. It is just totally beyond my level of expertise to guess how to start what the instructions are telling me.
lugoteehalt, Thanks, but your solution results in 6 to 10 mouse clicks or keyboard strokes to avoid two. I am needing to make a double click with ONE stroke. Must I say this: "I want to do as I do in Windows with Logitech software."
smoker, this sounds like a suitable solution, but really does not work if it works exactly as it does in Windows. I have tried the selection in Windows to open files with single click. It does make hover=single click and single click=double click, but makes trouble when selecting several photos from a folder containing many. There were other times when the single click option resulted in problems in Windows. I soon had to abandon that in favor of the Logitech software and center mouse button performing double click. I was not aware of any such option in Ubuntu or Linux Mint or other popular distros. Maybe I will try it to see if it behaves slightly different in Linux Mint and behaves satisfactorily.
Thanks to all of you for your suggestions.
edit: I have marked this thread as solved, not because I have found an answer to my question; but rather because I find my search futile. I have been searching for an answer to this (and many other linux questions and difficulties) for a few years on different forums with little to no success.
I wonder if I did something to have the Windows 7 logo appear under my name on my posts, I didn't intentionally do anything to have it appear there. I am NOT coming to a Linux forum to promote Windows anything. I am here in an attempt to find a replacement for Windows.
