Something doesn't work?

The Num lock should always be enabled. If it is disabled when you are attempting an alt code, it may cause errors or unexpected results in some applications. For example, Alt+4 could be interpreted as Alt +, ← which causes the browser to go back if the Num lock is disabled.
If your laptop keyboard doesn't have a separate NumPad, you should hold FN button with Alt button while typing the code.
This method does not work for Linux system, but it is possible to use Unicode.

Spanish Symbol

The Spanish language uses Latin alphabets. The pronunciation of the alphabet is phonemic, especially in comparison with the English alphabet, in Spanish you pronounce what is written. Besides the regular alphabet uses, the acute accent letters (á é í ó ú) are used. They indicate the stressed syllable, but they can be used to distinguish homophones. The Spanish royal academy is the institution responsible for governing the linguistic roles, and it also supervises any changes introduced into the language.

In November 2010 the countries of the association approved some changes in the Spanish alphabet including permanently removing the letters (Ch) and (ll) from the alphabet. After this decision, the Spanish alphabet is consisting of 27 letters, the usual 27 English letters plus ñ letter.

How to use and type Spanish symbol code?

If your keyboard contains separate NumPad, you should be sure that it is enabled. If it is not, press the Num Lock key to activate it then press hold down the Alt key on the left side. Type the number that represents that character or the symbol you want to insert and then release the insert key.
For example, for the greek letter omega Ω press and hold Alt and the type 0234 and then release.
There is another method that works only for word documents. In this method, you should type the characters first then press Alt and X. For example ( 0234 + Alt + X for greek letter omega ).
If you have a keyboard that doesn't have NumPad here is what will work for you. Find the Function key ( FN ) then presses and hold the function key while holding press and release Num LK key; then release FN key. This method will activate the numeric keypad in your laptop.
Then do the same steps as in the previous example.
Notice that in IBM code you don't use 0 (Alt + 255 ) before the code which is different from the windows generator that requires to add 0 (Alt + 0255 ) before the code.
