Copy, cut and paste files
Ctrl + C copies the selected files, Ctrl + X cuts them and Ctrl + V pastes into the current folder. They use the Windows clipboard, so they work with Explorer and other programs.
Delete to the Recycle Bin
Delete moves the selected files to the Recycle Bin.
Drag and drop from Explorer
Files dragged from Explorer or another program can be dropped onto the file list.
Back, forward and up
The path bar has Back, Forward and Up buttons. Each tab keeps a history of visited folders, and going back restores the selection. Alt + Left goes back, Alt + Right forward and Alt + Up to the parent.
Favorites dropdown
Hovering the star in the path bar shows the favorites. Click one to open it, or add and remove the current folder from the same list.
New window
Ctrl + N opens another window.
Notifications
Messages, such as what was copied to the clipboard or what a delete removed, show as rows at the bottom of the window.
Context menu from the keyboard
Shift + F10 or the menu key opens the context menu for the selection.
