An inventory management app was one of my first paid software engineering projects. Sometime in early 00s I had to rewrite it for Windows because the ancient DOS codebase had a bunch of issues running on then-modern Windows versions. I sat down with the users and watched how they were using the DOS version, including the common patterns of keyboard navigation, and then meticulously recreated them in the WinForms version.

For example, much of the time would be spend in a search dialog where you had a textbox on top and a grid with items right below. In the TUI version, all navigation was with arrow keys, and pressing down arrow in the textbox would move the focus to the first item on the grid. Similarly, if you used up arrow to scroll through the items in the grid all the way to the top, another press would move the cursor to the textbox. This was not the standard focus behavior for Windows apps, but it was very simple to wire up, and the users were quite happy with the new WinForms version in the end.
