MacOS Tip:

• You can drag and drop from the Finder to just about any app.
• Command + Tab let’s you bring a specific app to the foreground.

I just learned that If you start the drag and drop process (click and start dragging a file from the Finder) then Command + Tab to bring an App to the front, Drag and Drop respects this.

Very handy for grabbing a file from the Finder that you’d like to attach to an open email.
