How do i get this symbol on the keyboard?

The only one I can think of that looks like an “i” but it's not an ordinary “i” is U+2139 ( ℹ http://www.fileformat.info/info/unicode/char/2139/... ).

Can you not copy and past it into your question, or indicate its Unicode number? Or tell us what you need it for. There are lots of characters that look somewhat like “i” in lots of scripts.

i ｉ ͥ ⅰ ℹ ⒤ ⅈ 𝐢 𝑖 𝒊 𝒾 𝓲 𝔦 𝕚 𝖎 𝗂 𝗶 𝘪 𝚒 ⓘ ⁱ ᵢ í ì ĭ î ǐ ï ḯ ĩ į ī ỉ ȉ ȋ ị ḭ ı 𝚤 ɪ ᶦ ᴉ ᵎ ɨ ᶤ ᶖ ɩ ᶥ ᵼ ι ί ϊ ΐ ℩ ἰ ἱ ἲ ἳ ἴ ἵ ἶ ἷ ὶ ί ῐ ῑ ῒ ΐ ῖ ῗ 𝛊 𝜄 𝝸 𝞲 ⲓ і ї

These are versions of “i” and similar letters in Latin, Greek, Coptic, Cyrillic and the IPA. They do not look exactly the same in every font. You can copy and paste any of them into http://www.fileformat.info/info/unicode/char/searc... or into http://unicode.org/cldr/utility/character.jsp to get information about it.

Character Map.

Start - Accessories - System Tools - Character Map.

That is where you get special symbols from. You just look through all the symbols, and select the one you want, copy it, and paste it into place in your document.

ì í î ï ĩ ī ǐ

Well probably the most elementary one you'll be able to do for a center is a lower than signal < and a three however im no longer definite methods to do different symbols sorry however <three works for a center every person recongnizes that
