A list contains several matrices. Over all matrices (list elements) I'd like to access one matrix cell:

m <- matrix(1:9, nrow=3, dimnames=list(LETTERS[1:3], letters[1:3]))
l <- list(m1=m, m2=m*2, m3=m*3)
l[[3]] # works
l[[3]][1:2, ] # works
l[[1:3]][1, 1] # does not work

How can I slice all C-c combinations in the list?
