TMO 1.63 Noob Question

[Tweety]

I was playing TMO last night and I came across or should I say he come across me a merchant in Luzon Strait. After, getting close enough to a merchant I looked thur the periscope and noticed that this merchant didn,t have any flags on its mast. I couldn't tell if this was a nuetral, jap or what country it belongs to. I hit shift F11 to take a screen shot to capture a picture.

1. Should I shoot and ask questiions later, sink it, or let it pass.
2. What key is for taking screen shots.

When I tried to take a screen shot with shift F11, I ended with a capturing sequence.

3. What does caputring sequence do.

This was my fist patrol with SH4 UBM and TMO 1.63. So far I'm having a good time playing a really good game.

I want to thank all the modders out there, who do a wonderful job with modding.
