How to change the astronaut I control?

[Sokarrat]

Now Iim going to 'Space Center' every time I want to change the astronaut to control.

Is there a way to change the kerbal?

I read someone used "brackets" to roll the control of kerbals, but y tried (, ), {, }, <, >, [, ], ... and it has no effect. Using spanish keyboard layout.

Can it be 'binded' in a key?

Thanks.

Yes, you should be able to control it using [ and ]. Didn't work for me either (German layout).
You can rebind it in the options to something else and it will work.
