yes, the </> code box is not that nice / easy handling
i also often get stuck / try several times top bottom / bottom top
keep mouse pressed even add use arrow keys…
to get the whole thing selected for [ctrl[c]
worst case select the first line by mouse,then
press shift and go down by arrow key
or select first line by mouse,
go down to last line
hold shift key
and click end of last line.
some other forum with code entry have a [copy] button
