In the CMD interpreter on Windows, the ↑ arrow key replaces the current input (not sure what the accurate term is) with commands in the command history; commands that have previously been executed.
An odd idiosyncrasy of CMD is that on a fresh instance, when there are no previous commands in the history, the accidental pressing of the Up arrow key replaces the current input with the last "command" in the history; nothing, essentially clearing the input:
What's more, pressing the ↓ key doesn't return the previous command as you would expect; it's permanently lost. Essentially then, in the command prompt, the Up arrow doubles as a "clear input" key.
Can this be fixed at all?
