XYplorer Beta Club

Hit F2?

It needs refining or more experimentation, but with Sticky checked in Config, Colors And Styles, and Sticky Selection checked in Tools, Customize List, I could do control-space to start marking the files to copy, then shift-PageDown to keep marking files for the copy operation until I complete the entire group.
I believe that when I succeeded, I had Checkbox Selection unchecked, which was an oversight on my part.
This sort of thing could previously be done in FileDir, a program Jamal Mazuri designed for bline people, but which I haven't succeeded in installing on my Windows 11 machine.
In that program, a user can press F8 to start highlighting a group of files, navigate to the last file and press Shift-F8 to highlight all of the files within that region for moving/copying/deleting, etc.
Since I'll eventually be moving from Windows 7 to 11 on another machine, I needed a different way to accomplish this.
Incidentally, to make a long story longer, I discovered XYplorer because in a Windows 11 update, changing a filename in File Explorer would change the focus away from the file list, requiring 13 Shift-Tabs to get back to it.
Being able to do the mass copy operations is a bonus.
A Windows update fixed the focus problem in Windows 11, but I'm still glad I paid for XYplorer. It'll take forever to understand it, but it's a powerful and versatile program.

The script could be bound to a keyboard shortcut and should be integrated via
Menu - User - Manage Commands...
Category: Load Script File
Button "New..."
Caption: Select lines in between range
Script File: load "Select lines in between range.xys";

This should be ticked in the config:
Configuration | General | Refresh, Icons, History | Scripting | [x] Remember permanent variables

Press the keyboard shortcut once to mark the current line
and after reaching the final line, press it again.

It doesn't require any of the other former requirements (like Sticky Selection)...
