Hi,
Here is from
http://en.wikipedia.org/wiki/Keyboard_layout#US-International:
The US keyboard layout has a second Alt key instead of the AltGr key and
does not use any dead keys, and thus offers no way of inputting any sort of
diacritic or accent; this makes it unsuitable for all but a handful of
languages. On the other hand, US keyboard layout is widely used by
programmers worldwide.
U.S. keyboards are used not only in the United States, but also in most
English-speaking countries, e.g. Canada, Australia, and New Zealand. In the
United Kingdom, UK keyboards are used. See British and American keyboards
for details.
The US keyboard layout can be configured to type accents efficiently. This
is known as the US-International layout. Using the same layout as the US
keyboard, accented characters can be typed by pressing the appropriate
accent key, then the letter on the keyboard in its unaccented form. Accent
keys share the same key as ', `, ", ^ and ~.
Accent keys are activated by pressing it (without holding it), and next
pressing the letter that requires an accent. After the two strokes, the
single accented character would appear on the screen. Note that only vowels
can have accents in this way. If one wishes to use the normal single
quotation mark, caret and so on, one would press the accent key followed by
the spacebar. Accented characters can be typed with the following
combinations:
' the letter (é)
` the letter (è)
" the letter (ë)
^ the letter (ê)
~ the letter (ñ)
Thus, in this sense, the keys ', `, ", ^ and ~ are dead keys when first
depressed, then become normal keys functioning in the same way as keys on
the US keyboard if the spacebar is pressed.
There are also alternative US-International formats, whereby modifier keys
such as shift and alt are used, and the placement of the accented
characters are different from the placement of their unaccented
counterparts.
The US-International keyboards are used in The Netherlands.

How to Use StickyKeys
Key combinations require you to press and hold down two or more keys at
once. Single-handed typists or users who use a mouth-stick have difficulty
doing this. StickyKeys enables you to press a modifier key (CTRL, ALT, or
SHIFT), or the Windows logo key, and have it remain active until another
key is pressed.
To turn on StickyKeys, follow these steps:
1. Click Start, and then click Control Panel.
2. Under Pick a category, click Accessibility Options.
3. Under or pick a Control Panel icon, click Accessibility Options.
The Accessibility Options dialog box appears.
4. On the Keyboard tab, click to select the Use StickyKeys check box, and
then click OK.
