Insert the corresponding character at the cursor position 
and move the cursor one character to the right if the 
command is shorter than 254 characters.

Delete the character on the left of the cursor and move the 
cursor one character to the left. 
Left arrow key or <Ctrl+B>  Move the cursor one character to the left.

<Tab> 
Use the partial online help. That is, when you input an 
incomplete keyword and press <Tab>, if the input 
parameter uniquely identifies a complete keyword, the 
system substitutes the complete keyword for the input 
parameter; if more than one keywords match the input 
parameter, you can display them one by one (in complete 
form) by pressing <Tab> repeatedly; if no keyword 
matches the input parameter, the system displays your 
original input on a new line without any change.
