How to obtain t-values from mer objects

How about

summary(fm1)@coefs[,3]

Or if you are using the next-generation lme4:
summary(fm1)$coef[,3]

Sorry I should have stated a little clearer.

I do know how to see or print the t-statistic values at the R prompt.
What I meant to ask is how to extract the t-statistic values from the
mer slots.

I know how to obtain the fixed effects from a mer object:

(fm1<- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))

fixef(fm1)

or,

getME(fm1, 'beta')

But how can I obtain the t-statistic values for the fixed effects?

Thanks,
