In reply to Reach>Talent:
I had not intended to appear snobbish, although with hindsight I see that's how it might appear. No offence intended.
My point is whether your understanding or not of a particular word is material to your interpretation of the guide. In this case, the word is simply an embellishment - amusing if you get the pun, irrelevant if you don't. It doesn't affect the meat of the route description, which is to climb the slab.
Had the guidebook writer actually meant "go right" and used it as a clever pun to indicate that, then I would entirely agree with you. In that case not being able to work out a crossword-puzzle clue would materially interfere with your ability to interpret the guide. That would be poor writing.
The answer is not to dumb-down guidebook-writing but to use language carefully. And when guidebook-reading, to pick out the bits of the text that matter.
If you are going to complain about words in guidebooks, my biggest bugbear is "obvious", when all too often it isn't (as in "climb to the obvious tree" when faced with a small forest, or when the tree has long been cut down).
