Feature Request: keyboad like linux page up with inputrc

Hi,

Is it possible to add the possibility to go back commands like linux page up with inputrc please ?

Ex : when i write /system ssh, i would like use PAGE UP/PAGE DOWN to go back all commands starting by /system ssh

Is it possible to add shortcuts like CTRL + LEFT or CTRL + RIGHT to jump word to word in the command line

I think it will a save a lot of time in command line.

Thanks,
Xavier
