Breaking execution after continue command

[NarenB]

I am a WinDbg user trying to become familiar with GDB.

After issuing a continue command (resuming program execution), while the program is running, is there a way I can break into the program ? Something like COntrol-Break in WinDbg ?

Can we break in the first place ? Or after saying continue, the only way we break is when the breakpoint that was previously set, gets hit ?

Thanks !!
