Paste without formatting

This week I learned a new keyboard command, and I can't believe I didn't know it before now: paste without formatting.  It's perfect when you want to copy and paste text but you're only interested in the text, not the formatting.

Ctrl-Shift-V

(regular paste is just Ctrl-V)

So... as I was typing this, I was thinking it sounded a little familiar.  A quick search of the TechBits blog (using the search box on the blog) and sure enough!  We have written about this twice before (Aug 2013 and June 2016), and one of those posts was even mine! So how do I remember this for next time? What tips do you have for remembering handy keyboard shortcuts? Each time I learn it I think this keyboard is super-handy, but somehow I can seem to make it stick as part of my repertoire...)
