The unique feature of the ZX Spectrum keyboard characters comprises not only the single symbols (letters, digits, etc), but also the compound tokens (keywords, function names, etc) and all these are entered from the keyboard rather than being spelled out individually.
To obtain all these functions and commands, some keys have five or more distinct meanings, given partly by shifting the keys (i.e. pressing either the CAPS SHIFT key or the SYMBOL SHIFT key at the same time as the required one) and partly by having the machine in different modes.
Keyword NEW definition follows;
Starts the BASIC system off anew, deleting program and variables, and using the memory up to and including the byte whose address is in the system variable RAMBOT and preserves the system variables UDG, P RAMT, RASP and PIP
