One of the ways to avoid excise is to allow information entry where information is displayed. Asking the user to click a button to enter EDITING mode is excise – it makes the user work to fit the computer’s work processes.
Below is an example from citation management software Papers2 (which I love, overall), but I cannot tell you how many times I have clicked in the right bar where I can see the article’s information to try to edit the title, authors, or enter missing information (e.g. journal number, page numbers). To be able to edit that information, I HAVE to click the Edit button on the bottom right – because that’s how the software works, not because that’s how I (the user) think.
