I’m using: SWI-Prolog version 8.1.9.
One of my favorite windows in the graphical debugger is the Variable display window; the window the pops up when you double-click any variable in the Variable pane that is part of the debugger window.
I frequently have large lists associated with certain variables. I like to pop up the Variable display window and capture the entire contents of the variable for inspection in an editor. Unfortunately, there does not appear to be a button or right-click context menu choice that selects all the text in that window so you can copy it to the clipboard.
Instead, I have to click the mouse in the top of that window and while holding down the SHIFT key, scroll down for a long while as I highlight all the text in the window. If there were a select all option somewhere that would be a big help.
