/
Means Prompt, Range Delimiter, Stop, Exit, or Divide
Qedit uses the slash “/” in many places:
As the Qedit prompt character (e.g., /Add).
As the delimiter in a line range (e.g., 500/600).
As the delimiter in a column range (e.g., Change 1/2 “”).
// (two slashes) terminate input in the Add command
(same as Control-Y).
In Visual, / at the ===> line means Exit from Visual mode.
In the calculator, as a divide (e.g., =100/5).
