I wonder if this is a holdover from when you could navigate windows completely without a mouse using only the keyboard and shortcuts.
You can absolutely still do that now. At worst, you install power toys and use the accessibility option to move the mouse with arrow keys.





Not to question anybody shitting on windows ME, but keyboard-only navigation is a core windows feature, since it’s a consequence of accessibility
No extra software needed; installing the power toys just makes it easier and a little more discoverable.
