Yes, but a lot of commands behave differently for -h and --help.

Sure, but my ,s key sequence doesn’t just expand to sudo. It actually moves the cursor to the start of the current line, prefixes the command with sudo, and then moves the cursor to the end of the line. The idea is when you type a command which requires root privileges but forget to use sudo, you can just hit ctrl+p ,s to fetch the previous command and prefix it with sudo. This is what it looks like in ~/.inputrc: ",s":"^Asudo ^E"
