Getting cheatsheets via curl cheat.sh/INSERT_COMMAND_HERE
No install necessary, Also, you can quickly search within the cheatsheets via ~. For example if you copy curl cheat.sh/ls~find will show all the examples of ls that use find. If you remove ~find, then it shows all examples of ls.
I have a function in my bash alias for it (also piped into more for readability):
function cht() { curl cheat.sh/"$1"?style=igor|more }
