@Eslam-Farg ::
Hi, I'm using in this case ALT + #, that puts that
hash sign at the start of the line.

Those are the default keys (Emacs scheme). You start your Bash with the VI scheme turned on:
bash -o vi

added to ~/.bashrc

bashnavigation(){
cat <<EOF
     ^a         ^e       \\
  <-------   -------->    } Moving
    alt-b    alt-f       /
     <----   --->       /
       ^b    ^f        /
         <- ->
$ cp monfi[c]hier dir/
     <----   --->
     ^w     alt-d       \\
  <-------   -------->   } Erasing
     ^u         ^k      /
EOF
}

The arrow for "alt+d" is wrong. The shortcut stops at the end of the current word boundary and not before the next word
