ERASE START OF LINE

 Erases the current line, starting with the character left of the cursor
 until the start of the line.  If you are already at the start of a line,
 nothing is erased.

 Key:   EVE defines CTRL/U as ERASE START OF LINE.

 Steps:

    1.  Put the cursor to the right of the text you want to erase.

    2.  Use ERASE START OF LINE.

 Usage notes:

 o  At the end of a line (carriage return), ERASE START OF LINE erases the
    text on the line, leaving the cursor at the start of a blank line.

 o  To insert what you erased, use RESTORE LINE.

 o  Setting the EDT keypad redefines CTRL/U as Delete Start Line, which is
    slightly different from the EVE definition.
