The only radio button that has a non ambiguous accelerator key is Clone (alt+c).
So how about a compromise - number the radio buttons 1-5 and make the digits the accelerator keys. Then they won't be accidentally reached via one too many alt+r, alt+g, alt+t or alt+e sequences.
This wasn't the first time this happened to me. But previously I spotted the radio button had been set before pressing Enter (OK), so I could hit Escape (Cancel) and start over. This time I missed it.
