Or my superior workflow is Alt-u or hold U, which is a single shortcut/keystroke, so you lose there as well

The other issue with your attempt at solving undo without undo is that the deletion doesn't become part of redo, also a single word with a typo could be in the middle of a paragraph where you navigated with a trackpad, while ^W would delete near the current cursor position

You don't need magic to fix the ubersimplicity of current defaults, just a bit of openness

^W is ctrl-W.

So what? How does it address the issue I've described?

[fwip]

It's the same number of keypresses as alt-U.

So now it's not "more keystrokes" as you originally claimed (and it's a higher number of keypressses vs holding U), and you still haven't addressed the issue with ^W I've described
