How do I print letters with sine fadas?

Press the Alt Gr key and the required letter e.g. Alt Gr + a = á 
For a capital letter, press Alt Gr, Shift and the required letter e.g. Alt Gr + Shift + a = Á

Note: For some keyboards, pressing Alt Gr and the letter i does not give í. 
If you experience this problem, press the Ctrl key and the single quotation mark (’) and the i key i.e. Ctrl + ’ + i = í. 
To get a capital Í, press the Ctrl key and the single quotation mark (’) and then also press the Shift key and the i key i.e. Ctrl + ’ + Shift + i = Í
