When using the console (or edit) line interpreter the DELETE button does not work. Other line editing options work (Home and end).
So:
I tried to execute:
"help graphics"
I get an error stating that graphics is not a know variable
I press up and edit the line
I insert the " before and after the graphics text.
I still get an error because I typed " help "graaphics" "
I press up and home and press DELETE after moving the cursor to the first 'a'.

Workaround:
Go the the next letter and press BACKSPACE.

Environment:
Linux (Ubuntu 23.04)
