The issue happens when you're not "switching", but co-existing across multiple platforms.

For work, I use a Mac as my daily computer, but also use Linux at home, and a ChromeOS for travel. My Mac is heavily customized to behave like my Linux desktop, but there's little hope for ChromeOS, which means all my muscle memory is gone.

I wish we'd have better standards, and at least a universal way to customize keyboard shortcuts. Unfortunately we're far away from that. Even on Mac and Linux.
