XYplorer Beta Club

Is it possible, please, to add to Custom event actions > Right click on white in file list, a new item:
Standard Windows menu.

Currently not. Never found the correct way to show that menu. Might give it another shot in the 64-bit version later.

... or at least a slim version of menu, named Pop up Slim Edit menu, containing only:

Paste
Undo (copy, move, delete, rename)
Redo (copy, move, delete, rename)
Search Everything (from voidtools, if installed)
New > Folder
New > Shortcut
Properties

The breadcrumb bar hamburger lets you build any menu you can dream of.

Support for creating new shortcuts (.lnk) would be useful. Having it available as a command (e.g. #897) would be even better, so it could be used from toolbars, hotkeys, scripts, User Commands, and menus.

1) Right click on white in file list | New | New Shortcut...

2) #241: Edit | New | New Shortcut...

Sorry, mentioning .lnk may have been misleading. I was referring to the "New Shortcut" item itself. Currently only #240 (New Items) is available for this kind of use case.

Sorry, I still don't get it.

I was referring to Explorer's folder background "New" menu (ShellNew), not XYplorer's own New menu.

What do you want to do that you think is not possible?

Many new users have asked me where to find this menu item. I usually tell them to add templates to the NewItems folder. It would be nice if Explorer's ShellNew items could be added to the folder background context menu.

I never really got it to work correctly but there is an undocumented way to show that right-click-on-white context menu. Tweak: Just tried it in the 32-bit version and it works quite well.
