Back in the day when I actually had a desk and walls on which to pin things, I printed out and stuck cheat sheets from the 4 languages in effective use in my context: SAS, R, python and C.

The lag/effort was/is far less than google if the info is right there, and I personally found I kept having brain farts where I'd temporarily forget what language the thought I was having was actually in, and could quickly touch base again by referencing the cheat sheet without bringing up the (often distracting) web browser...
