[TxMt] select whole function?

Hi, Programming for R (stats package) the user often wants to select a whole function (usually in order to execute it in R)

my fun <- function(param,..){ # your code }

cmd-shift-B will select the next-out level of brackets, and, if repeated, will eventually select the outer-most brackets. But to execute the function, one needs to select the whole of that first line of the function definition.

Is there a command to do that?

the command would function like repeated executions of cmd-shift-B until the there is no outer bracket to find, then expand the selection to include ^ of the first line
