I used to do sudo !!, but then I’ve started learning the shortcuts of my shell a bit more - Ctrl+A jumps to the beginning of the line, which, technically speaking, is a saving of 1 (!) keystroke, compared to Shift+1+1.
This has also led to discover that emacs is actually much more useful compared to vim as it uses the same shortcuts.
If you already submitted the command, you’ll have to hit Up first to have a line to jump to the beginning of, though, so it’ll be the same number of keystrokes either way.
I do the same thing you do, just with vi-mode keystrokes (up, then esc-I).
