I would like to request mnemonics for the popup menus and submenus (e.g. in Transfers, Tree views).

Ctrl selection is not working in the Files tree view: Ctrl + Space does not toggle the selection, Ctrl + Up/Down does not move the current line.

I would also request a shortcut to toggle the download status of the selected file(s) in the Files view. It can be a single shortcut (e.g. Space or Insert), or separate shortcuts to turn it on and off. It should do the same as clicking the Download checkbox with the mouse, only for all the selected files, and preferably (also) from the keyboard.
