Plus while it’s very convenient for tools that support autocomplete of their parameters, but not all do. So sometimes you just fall in the habit of assuming they don’t.
- PowerShell has Ctrl+Z
- Bash has Ctrl+/
- Fish has Ctrl+Z and Ctrl+/ both
not sure about others, surely if you're using busybox ash this won't work (no line editing will work), but I'm sure most shells have some sort of undo, as long as they have any line editing at all.
Hopefully I’ll remember that next time I need it.
