I'm basically looking for a way to show a dialog/menu/list listing all the ftps I have, possibly without using the mouse (I don't like to use the mouse when both hands are on the keyboard).
That's the right command. (Or Go FTPSITELIST FTPSITEICONS if you want icons.)
It generates a list of FTP sites within the toolbar/menu it's in, though. If you bind it to a hotkey it's meaningless. You need to bind a hotkey which opens a toolbar or menu with the command inside it, like in the recent thread about Recent and Favorites lists. Or just use the Alt key combinations and underscored letters to open the FTP menu (assuming you haven't deleted it from the default configuration). Alt-P does it by default.
Ok, I understand how to add such a list to a menu, but I can't find a way to bind a key to show that specific menu, or add a specific context menu (that would only show the FTP list for example).
