A resume is not actually a letter, hence it doesn't require a salutation. You can, of course, also write a letter to a specific employer, to which your resume can be attached. In that case you would be using a normal business salutation, Dear Sir or Dear Madame as the case may be.
No a greeting. A salutation is what you write at the end of a letter.
Tap the up arrow to write the next letter in upper case. To write everything in upper case double tap the up arrow. To change back to lower case tap the arrow again.
Upper case:A , BLower case: α , β
yes
The salutation itself ("Dear Ms. Jones") should not include your return address. On a business letter, the return address can go in the upper right corner of the cover letter. The salutation goes below the delivery address.
Doe, John A., M.D.
You could go with "Friends:" or write "hey everybody!"

Website names and Email user names are NOT case sensitive, meaning you can write them in lower or upper case, it wouldn't matter. Only passwords are case sensitive. If you meant to ask why they are generally written in lower case when displayed on a website or other medium....they just look better that way.
Use the name of the person who wrote the letter, and write a formal letter. Use the salutation "Dear Mr. ____" or "Dear Mrs. _____" as a salutation.
