One of the things that I don’t like about FV is that the shortcuts cannot be customized. So I use AutoHotkey (AHK) to create my own shortcuts. AHK does that by sending Alt keys to the app, simulating using the keyboard to select menu options. FV 24.1.1.0 no longer responds to the Alt key when using the Classic UI menu, which breaks my custom shortcuts.
If you downgrade to FV 23.8.26.0, enable the Classic UI menu, then install AutoHotkey, and install this script, F8 will open the Create Folder panel in FV.
