Problem: Some dialog boxes or pop ups must be closed by clicking either "Ok" or the close window button which, when they pop up in a far corner of the screen can add time and unnecessary effort to the workflow.
Solution: Make all pop-ups and dialog boxes consistent - Enter key means "OK" or whatever the highlighted button is, and the Escape key means "Cancel" or closes the window. This way us CAD workers can keep a smooth workflow.
Little things make a big difference.
