However, if you wear bifocals and usually tilt your head back in order to look down through them at the monitor, lower the monitor (or raise your chair) so that the monitor sits 15 to 20 degrees below eye level; note that this may require you to tilt the screen slightly upwards toward your face.

Keyboard trays can lower the keyboard and mouse, and help keep them within easy reach. Good ones allow you to adjust the position and angle, as well.

If you have a 10-key on the right side of your keyboard, you may want to use your mouse on the left side; this centers the part of your keyboard that you use most. You can also alternate left and right-sided mouse usage to dilute the effects of repetitive use. Choose a mouse which is the right size for your hands.

If you touch type and do a lot of transcription, consider placing the document holder in front of you, with the screen to one side. The main focus of attention is then straight ahead with occasional movements to view the screen. Another option would be to provide a lectern that is positioned between the keyboard and screen.

In any language, minding your manners shows respect. Using polite words and phrases in Arabic, even if you don't know any other words in the language, communicates that you respect Arab culture. Some words to learn include: "Al-ma'dirah": Excuse me (if you're asking someone to move) "Aasif": Sorry "Miin faadliikaa": Please "Shukran": Thank you "Al'afw": Reply to "thank you" Traditionally, men and women do not touch each other at all when greeting, unless they are close family members. Some women are willing to shake hands with men, particularly in more formal contexts. However, if you are a man, you should let the woman take the lead. Stand away from the woman as you greet her. If she is willing to shake your hand, she will extend her hand to you. Don't automatically extend your hand first. If she clasps her hands together or places her right hand over her heart, that is an indication that she isn't willing to shake hands but is nonetheless pleased to meet you. When greeting someone of the same gender as you in a formal context, such as in a professional environment or for school, shaking hands is common. It's still a good idea to let the other person take the lead and offer their hand first. Always shake with your right hand, never your left. The left hand is considered unclean in Arab culture. Placing your right hand over your heart indicates that even though you're not going to touch the person, you're still quite pleased to meet them. If you have Arabic friends of a different gender, this is an appropriate way to greet them. Because men and women who aren't related to each other typically don't touch each other when greeting, this gesture is a way to signify your attachment to the person you're greeting without hugging or kissing them. In Arabic culture, touching noses is not considered a particularly intimate gesture and is frequently done between two men as well as between two women. Another gesture popular in some areas is to place 3 kisses on the other person's right cheek. These gestures are typically never appropriate with someone of a different gender unless you are related to them and have a very close relationship. Even then, many Arabs would not consider such a greeting appropriate in public. Elders are greatly respected in Arabic culture. A kiss on the forehead honors them and shows them respect. Reserve this gesture for elders you know well, or who are related to someone you know well. For example, if your Qatari friend introduces you to his grandmother, you might kiss her on the forehead when greeting her.
