that's great. I usually use the context menu on MacOS and the "Define" option on long press on iOS

That said, trying to use long press on iOS (or whatever it actually is), is one of those places that often drives me nuts. I don't know if the issue is a specific app or the OS or what but sometimes I want the popup menu to appear and I can't get it to appear. Or I do something to make it appear but it doesn't appear for x hundred milliseconds, during which I think it didn't get my gesture so I start a new one, just as it's finally responding in which case my new gesture dismisses it. Repeat 3-4 times before I'm ready to tear my hair out

It also shows why canvas based websites suck. Open Google Docs, select a word, press Cmd-Ctrl-D, ... nothing. Try it in gmail (which is not canvas based) and it works.
