You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.

move cursor to beginning of command line
Pressing Ctrl combined with 'a' will move the cursor to the beginning of the command under bash (other shells?).

Still Ctrl+A can be very useful when you want to edit something at/close to the beginning of the command line.
