limit evaluation



New Maxima user here.? I'm going to swallow my pride and ask this. Sorry if this is obvious, but I've spent about an hour trying different things and looking at examples and reading the docs and I can't figure out how to get Maxima to tell me that the answer to the limit is "1" (and hopefully to show me how it got that answer):

(%i3) limit(sum(1/10^k,k,1, n),n,inf,minus);
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ???n
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ====
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? \? ? ? 1
(%o3)? ? ? ? ? ? ? ? ? ? ? ???limit? ? ? >? ? ---
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? n -> inf- /? ? ???k
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ====? 10
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? k = 1
(%i4) 


Is there a doc somewhere that just contains a gazillion working examples of Maxima's various capabilities??
