The reason for this is complicated, but basically telnet is still based on the terminals of a decade ago. These had various modes of operation, but standards were not always completely understood. The best and most reliable standard for a terminal is called 'vt100', and is the standard mode which window's telnet operates in. This mode did not have cursor keys. In vt100, you can still have something like cursor keys using the control key, and these are

Other control key combinations are also programmed to do special and useful things in the shells we will be using - more of this later.
