> While it’s true that if you randomly pick a GUI and a TUI application, the latter is more probable to be fully keyboard-driven, this does not tip the scale in favor of developing TUIs over GUIs3. What it does is highlight the inadequacies of keyboard navigation in many GUI applications.
Something to consider is a terminal that has keyboard navigation of its own. Through a terminal shortcut, I can move the cursor at will and copy any text at all, even if it's part of the interface of a TUI. If I want to copy the filepath of the file I'm working on in vim to then use in a shell, for example, it takes like 5 keys to copy it straight off vim's statusbar. A graphical text editor can display the filepath in a tab or something, but I can't copy the text off the tab.
I don't know if I'm alone in this, but it's very frustrating to want a piece text, see it in front of you, and you can't copy it because the developer for one reason or another didn't implement copying of that text, so you have to type it out even if it's right there.
Sometimes it seems on purpose too. For example, when a game on Steam gets updated terms of use, you get presented with a window showing the terms, but you can't copy them to save them. It's like the purpose is to just accept and forget the terms. A TUI can't prevent the user from copying text by its very nature.
Any terminal can implement this kind of arbitrary-text keyboard navigation on its own and have it work for all TUIs. Were e.g. GTK to implement something like this, it would only work for GTK apps, not for all GUI apps. This is exclusive of TUIs because TUIs are text-driven while GUIs are pixel-driven.
