less help: more help! I use the shell since forever, and yet I keep learning new things. Ironically, being very familiar with a tool seems to be the perfect recipe for not knowing it deeply. A thing that typically happens, in my case, is to systematically work around minor annoying software behaviours, without even trying to understand if there's an 'official' way to get rid of said annoyances. Take less(1), for example: searching for a term results by default in such term being highlighted. This is a very useful feature, until you're satisfied with the search results, and you want to turn highlighting off. Official way: ESC-u Stupid workaround: search for something else, hoping not to find any result. In my case, I tend to use the stupid workaround, because the official way is not wired in my muscolar memory. Specifically I tend to search /noh, simply because :noh is how you disable search highlights in vim, and that is in my muscolar memory. Yesterday I realised how stupid it is to use the work-around for something that *must* be a feature, and that's why I looked into the manual. I found about ESC-u, and about more useful features I didn't know. For example ^K (keep position) or ^R (no regex, faster!). There is always some hidden pearl in the user manuals!
