In the Mac OS X operating system, when you copy content from one application, and paste into another, the source styles, in addition to the content, is copied into the destination. Unless you’re expecting or desire this behavior, your workflow is interrupted and you’re left with a bit of a mess to clean up (the effort of which relates to how quickly you discover what happened).
Most style-aware applications support a “Paste and Match Style” option, but some don’t (like “sidenote”, the application in which I’m writing this post.) For those, we’re kind of stuck.
Based on how I work (mostly in plain text), as well as most people I know, a preferred approach would be:
“Paste and Match Style” should be the default behavior of the basic “Paste” function.
The current “Paste and Match Style” option should be renamed and re-functioned “Paste with styles”.
Applications that are particularly interested in styles (page layout applications, graphic design applications, etc.), could, on pastes which include styles, simply prompt the user, “Include styles with this paste?”
