This is massively important, especially for line of business apps or tools that the user touches hundreds pf times a day. GUIs are great when there are multiple, equally likely paths that the user could take. But LOB apps tend not to be like that: there is a mainline path (or very small number of paths) that dominates all others, and apps that let the user keystroke/tab/enter their way through these hot paths are waaaay fast. For US people, look at how fast the employee in your local Costco can look you up on their ancient-looking text app. You can do this in a GUI, or at least, you could in native apps, to some extent, with a series of tab presses to traverse the interface, and in the peak VB5 era this wast kinda ok, but not great, and webapps are a hot mess for this use case. If I'm shopping for flights, a gui webapp is great: lots of paths are valid, and i can poke around. If I'm a gate agent looking for the last seat on the plane out of O'Hare, I want speed.
