How to write diacritical marks (accents, tildes, etc.) in Spanish on Microsoft

How to Type Accents and Tildes
For newer Microsoft programs, most accent marks can be written by:
Holding down the Ctrl key and then pressing down the hyphen key.
Release these keys and select the letter you want to be accented.
If this does NOT work, try the follow instructions.

~ = tilde
Ñ = control + ~, n
¡ = control + shift + alt, !
¿ = control + shift + alt, ?

When in Microsoft Windows, double-click on Insert-Symbols.

You'll see a window with a chart of several symbols appear.
Next, click on the desired symbol.
For example, if I wanted to write an "ñ",
I would click on that square, and then on the button, "Insert".

BEFORE selecting "Insert",
look at the lower right-hand corner of the window to see if a "Keyboard short cut" is indicated.

For the "ñ" it would say, "Keystroke: ALT+0241".
This means the next time you want to write this character (ñ), instead of going through this process, you could just:
• Hold down the Alt button and also type the code 0241, and an ñ will appear on your paper.
You can explore the symbols available on the INSERT chart, to learn their shortcuts, and write them down on a piece of paper to refer to in the future.

Here is a list of diacritical marks keyboard short cuts you might need in Spanish:
á = ALT+0225
é= ALT+0233
í= ALT+0237
ó= ALT+0243
ú= ALT+0250
ü= ALT+0252
ñ= ALT+0241
«= ALT+0171
»= ALT+0187
