So using find was obviously a simplistic example. I know ctrl F is near-universal for a regular find operation, but let's imagine some other specialised feature of, say, a CAD application. "Find vertex in selected model" perhaps?

Oddly enough, I just discarded MacOS for a similar reason: yes, ctrl f is for "find" but, unlike on any other platform where ctrl shift f is "find in all files in project", on MacOS that is cmd shift f. WTAF, there goes my muscle memory out the window. In fact, the "when is it ctrl and when is it cmd" threw me for such a loop that it impacted my performance. Now that I'm back on Linux, the tool disappears and I can just do my job. Ahh.
