 Alt keys
 Windows key
 Option key
The remaining keyboard keys not listed above are not necessarily
assigned to a specific finger for pressing them. Instead, you can use
whichever finger is easiest or most comfortable for reaching and
pressing those keys.
How many fingers should be on the home row?
With the four fingers of both hands on the home row, there should
be a total of eight fingers positioned over the home row.
Note
Most don't consider the thumbs "fingers." However, both
thumbs should also be hovering over the spacebar.
Should my palms be resting, or should they be
raised?
When typing, your palms should be raised and not resting on any
surface, including a wrist pad, and held at a 10 to 30-degree angle.
Raising or lowering your wrists too much in either direction or
resting them while typing can cause stress and lead to carpal tunnel
syndrome.

6. Other keyboard safety tips
While keeping your palms raised while typing, there are also other
tips you can follow to help prevent carpal tunnel and pain while you
type. Keep the following suggestions in mind every time you type.
 Keep your keyboard home row height as close to elbow
level as possible.
 Center the spacebar with your body.
 Do not angle or bend your wrists. While typing, keep
your wrists elevated and as straight as possible.
 Avoid hunt-and-peck typing as it causes strain on the
neck from having to look down at the keyboard often.
 Don't use more force than needed to press the keys;
you don't want to hit the keys, as it could lead to
keyboard damage.
 When you're not typing, make sure to rest your arms
and hands. However, never rest your arms, hands, or
wrist on a sharp edge.
 Take a break from typing every 20 to 30 minutes. If you
have a hard time remembering when to take a break,
set a timer or drink lots of water, forcing you to go to
the bathroom more often.
