Thanks!!! It's working now. But how to bind this to a key?

I have a big problem with Altirra configuration. I've installed the emulator, configured system, chosen peripherals - Ultimate 1MB and SIDE2 and flashed firmwares. I've made VHD disk. Everything is working fine. I can run xex and atr files. There is a problem with multi ATRs games. I've mounted the ATRs, changing with CTRL+S is working, I can see it in Altirra, but when I run games nothing happens, when I press CTRL+S. I now the ATR Swap Button is on real SIDE2 Cardridge, but I don't know what to do with emulated SIDE2. Sorry for my English.
