There are mods available to personalise the keyboard controls available on subsim if you need to change them to something more ergonomic. I actually use a speech recognition program called shspeech which I have working on both sh3 and sh4. You give the crew verbal orders through a headset or microphone. The immersion factor is very good. It takes a little patience and a bit of tweaking though. If you can speak english or german well it should work ok for you.
