You can switch to the NppFTP window using a keyboard shortcut, by adding a shortcut for the Focus NppFTP Window
option.
To do this, open up the Shortcut Mapper (Settings -> Shortcut Mapper
), then click Plugin Commands
and scroll down to the option.
You can then switch back to the other view by defining a shortcut for the Focus on Another View
option, available from the Main Menu
options under Shortcut Mapper.
(There's also the Move to Other View
option too if you need it).
