Like some others, I don't have a list of cheatsheets except my bash history and my browser bookmarks. My bash history atm contains 4575 unique entries (I reset it a few weeks ago). It is like L1 cache to me for accessing most frequently used commands. Beside that I press `*` then Space in browser bar to search my previously bookmarks (I add keywords to them upon bookmarking by modifying the title). Beside these two, nowadays I write Makefiles in every project I work on. That way one can consolidate all commands that otherwise would be forgotten or scattered in configs, in one place.
