Not the exhaustive fifty-shortcut cheat sheet nobody memorizes, just the six that actually changed how fast I work: window snapping, clipboard history, quick app switching held for a second longer to see all windows, a screenshot-to-clipboard shortcut, tab reopen, and a dedicated shortcut for pasting as plain text.
That last one alone saved me from hours of manually stripping formatting out of pasted text over the past year. I didn’t even know it existed until a coworker mentioned it offhand.
Six shortcuts, genuinely used every day, beats a printed sheet of fifty I’d never reference again after day one.
