There is no bento button, not in any viewer, least of all one that's basically a clone of viewer 1. I've been told by a fossil perma-noob that his computer was 'too old and weak' to display mesh so he wouldnt switch to a mesh viewer', only to find when he stated the machines specs, that it was faster than mine and had twice the memory, which I told him. I comment that you are using what is essentiaslly an outdated badly supported viewer, and you assume i 'can afford a brands new computer' but in fact, I can't, my pc is old and obsolete but I still have less trouble running SL than a lot of the complainers, BECAUSE I pay attention and don't just throw my hands in the air and scream 'waaaah it's not the good old days anymore'.
That wasn't sarcasm, it's a statement of what is pretty much a fact.
