$ Left arrow key or u

try on your machine

The command "Left arrow key or u" refers to two input options for a user to navigate or interact with a system, particularly in a text-based or command-line environment.

Left arrow key: The "Left arrow key" typically refers to a key present on a computer keyboard that allows the user to move the cursor or insertion point to the left in a text document or input field. By pressing the left arrow key, the cursor or insertion point moves to the previous character on the left.
u: The letter "u" represents a keyboard input. In this context, it may refer to the letter "u" key on a keyboard, which can be used as an alternative to the left arrow key. Pressing the "u" key may also prompt a specific action or function in a particular software or command-line interface.

Both options - using the Left arrow key or pressing the letter "u" - can be used interchangeably to perform the desired action specified by the system or software.
