(This really has nothing to do with the PPC architecture, the problem
exists on all X11 platforms, but not on Windows because it isn't
implemented there...)

The data.entry function is a very old one and hasn't been updated for
a long while. Apparently most people don't use it much. As long as
data are purely numeric, it does sort of work, also for data frames
although it has an annoying habit of turning them into lists (fixable
with class(object)<-"data.frame"), but as soon as factors are
involved, everything comes to a halt.

It also contains a couple of pretty nasty bugs, and is very limited in
basic useability aspects (as you note, there's no "go to end" command,
and there's also no way of shuffling rows/columns around, inserting
things in the middle, etc.)

Don't be too surprised if this gets changed substantially in the future.

ls()... If you really want only the functions, try something like:

functions<-  
function (...) 
{
    names <- eval.parent(substitute(ls(...)))
    prnt <- parent.frame()
    fcts <- sapply(names, function(s) is.function(get(s, envir = prnt)))
    names[fcts]
}
