Here's the entry in the character map... that should give you some information.

Most word processors allow formatting a single character as subscript.

You can use compose keys.

E.g. Right-Alt _ 2 gives ₂ in CO₂ (actual key strokes - Right-Alt, Shift & -, 2)

or for superscript Right-Alt ^ 2 gives ² (actual key strokes - Right-Alt, Shift & 6, 2)

Your compose key may be set to something different

How can I install the character-map?

I don't have a "Right-Alt", only the left one.

And that's the upper small 2, but I'm looking for the lower one.

smurphos is quite correct, the sequence to get a subscript ₂ can be achieved with the Compose Key, which you have to set in System Settings -> Hardware -> Keyboard -> Layouts -> Options. You can select any key you like as your Compose Key. My preference is to use the Caps Lock key. Once set, it is always ready to be used and you can type these and many other letters: é, ë, ê, ç, ß.

After setting the Compose key I would use CO followed by a tap on the Compose Key, then _, then 2. This results in CO₂

Edited for clarity

Should be pre-installed in MATE and in your menu under Accessories - if not apt install gucharmap. MATE also has a funky applet called character palette that you can add to the panel and customise to quickly add commonly used special characters. If you experiment with it be sure to read it's Right Click > Help menu to get the most out of it.

Then there's good old unicode:

ctrl+shift+u2802

I have always used subscript and superscript for this sort of thing and then reduced the font size.

No, it's still not the wanted lower small 2.
Looks more like a dot.

If you want to use Unicode then the correct code is "u2082"

Press and hold Shift+Ctrl, type u2082 produces ₂ when released.

Using the Compose Key is much simpler and quicker.

Thanks for the correction Kyphi, keyboard dyslexia here!

ctrl+shift+u (release) then 2082 also works--types the unicode character at the next keyboard action. I've never used the compose key, I assume you are talking about "alt/gr" which I don't have on u.s. keyboards. I have found unicode handy for lots of not often used characters.

Bob
