Is there a same possibility as the Total Commander ctrl-B

Help & Support
1

so I would like to see all the files from the subfolders in one lister.

View > Flat View in the default menus. You can assign hotkeys if you like. The Flat View toolbar in the Buttons & Toolbars forum may also be of interest.

You can map that to CTRL + B if you like, just...

Help -> Keyboard map -> New hotkey

Set FLATVIEW=Toggle,MixedNoFolders
