As you all know, the spectrum 48k has a built in BASIC
interpreter in it's OS, thus the possibily of typing programs made
in this language, unfortunately, to save extra memory, Speccy used
the extended ASCII characters to encode the keywords. This way a
sentece like PRINT occupies one byte of memory instead of five.
This has an annoying inconvenience, since to type a sentence you
have to press the corresponding key in the proper mode.
The main trouble is that such correspondence was printed
in each original Spectrum key, unlike the keyboard we use for emulation.
Thus, you have four ways of typing programs in the emulator.
1. Remembering every single correspondence. I did
know them some years ago, but I've forgotten them by now.
2. If you don't know them, you are still in time to
learn them, although this option is quite painstaking.
3. Make stickers and put them in your PC keyboard.
Not less difficult than the previous one, but you can show what
good Specchum you are :).
4. Pressing F1 and looking for the desired command.
If you haven't typed nothing in a Spectrum, and don't
know much about it's modes, you might find useful the following
