To type in Inuktitut syllabic characters with the legacy (non-Unicode) fonts ProSyl, Nunacom and AiPaiNunavik, all you need to do is to set the font in your application (MS Word, etc. - for input in web pages, this will be set for you) and type in the characters, following the proper keyboard layout for the font (see below). A keyboard layout1 is how the characters are associated to the keys of the keyboard. For example, the inuktitut syllabic character (tu) is associated with the key labelled 'G'. When you have any of those three fonts set as the current font, typing on the key 'G' will print the character in your application.
These two fonts do not need a special keyboard driver2. They use the same driver as regular fonts like Times New Roman. For example, in ProSyl, the code of the character is the combination of the ASCII codes of the two characters ` and t that must be successively typed in order to get it, that is, 0x60 0x74. All syllabic characters in ProSyl and Nunacom are accessible through the regular keyboard driver.
ProSyl and Nunacom have very similar layouts (also very similar to the Unicode Inuktitut Keyboard Layout Levels 1 & 2). For the most part, the basic syllabic characters are associated with the same keys in both fonts. The differences lie mostly with some punctuation marks and with how the dotted (long) syllabic characters are produced. For example, to print the character in ProSyl, you have to type in the keys labelled ` and W, whereas in Nunacom, you have to type | and W. Of course, you could use any 'dot' key (like ` and |) with any basic syllabic character, but the placement of the dot might not be optimal with that character.
The two following figures show the keyboard layouts for the fonts ProSyl and Nunacom. They also indicate which 'dot' key to use with every short syllabic character to get the corresponding long syllabic character.

Install the fonts and the drivers
In the icon box at the bottom right of your screen, there
is the icon
that indicates the active keyboard driver. When you click on
icon, you get the list of all the keyboard drivers installed on your
computer. Select NO.
This brings you to the first level of the AiPaiNunavik keyboard layout (see 'regular' in the figure below). Pressing the keys Shift, Alt, Alt+Shift will get you to the three additional levels.
