as for me, it has been,

history | grep searchTerm

ctrl+a and ctrl+e move to the beginning or end of the line.

also, installing fzf was a massive productivity booster while doing things like ctrl+r (https://www.youtube.com/watch?v=qgG5Jhi_Els)

Update:

I 'll use the comments below to write a summary article here, these might be more useful than random commands on the web as these are likely heavily used by the community here.
