Title: What do all capital letters typically refer to in writing?
Question: In many error messages and conversations, I come across words in all capital letters, as demonstrated in the examples below.   ERROR: Please type your e-mail address.   or   ME: I can't make it   SHE: I HATE you.   ME: I'm soo sorry.   What is the typical meaning of or reason for these words written in all capital letters?

Answers:
sents: text: All caps are typically used for either of two reasons: Visual Style Capital letters are often used on covers of magazines, in logos and artsy-typography, usually to emphasise the visual style of the letters themselves, rather than the word.
text: ( Example Image )
text: Contextual emphasis: Capital letters can be considered a third form of emphasis, among Italics and Bold text.
text: They are used to denote a louder, almost shouting (and in many cases actually shouting) pronunciation.
text: This is done by tabloid newspapers, for example:
text: Political Correctness Gone MAD!
text: (in this example, the exclamation mark is used, erroneously, to add even more volume)
text: Legal documents sometimes use capital letters to denote areas of special importance.
text: They are, presumably, trying to avoid the area being overlooked by the reader, by making it stand out from the rest of the text.
text: This product comes with NO WARRANTY.
text: There are also technical reasons for using capital letters.
text: Here are just some examples of this: Typesetting systems (old computers, stencils, ...) that don't allow for italics or bold text may encourage some to use capital letters instead Capital letters to denote a SURNAME as opposed to a first name (according to wikipedia, this is done in francophone countries)
text: There are suggestions, some call it a consensus, that upper case text is harder to read than correctly capitalised text.
text: This, to my knowledge, first manifested itself in public policy when British road signs were changed in 1957.
text: The Worboys Committee proposed a new type face called Transport , using lower case letters for the first time.
text: This is based on the idea that one reads the shape of the word rather than each individual letter.
text: The All caps article on Wikipedia summarises the evidence for this.
text: It's not even always a good idea to capitalise acronyms and initialisms, as illustrated by this ridiculous example: Have they turned on the LASER yet?
text: Rhodri rightly says that this is uncommon and only happens to de-facto words.
text: As Jimi pointed out, ALL CAPS in email and instant messaging conversations is considered shouting, and people who use it extensively are considered trolls .

sents: text: Lo, these many years ago, I took a typing class (manual typewriters, for a true sense of age!).
text: We were instructed to use ALL CAPS as a substitute for bold and underline ( _ _) as a substitute for italics .
text: When I started going on line (long before publicly available Internet), I was taught to surround text with asterisk (*) when I intended bold and with underscore (_)
text: when I intended italic .
text: If you pay attention to the markup used in this forum, you can see how those conventions have been honoured and expressed over time and through changing technology.
text: In English classes (native English, not ESL or second-language) we were also taught to use ALL CAPS to separate the 'description' from the 'real' text.
text: So, in your error message example, ERROR: is telling you that what follows is an error message as distinct from a warning message (WARNING:) or a purely informational message (INFO:).
text: A similar concept applies to dialogue the way it is normally written in plays.
text: As a side note, I was also taught that underline was introduced with the typewriter and that previous to that scribes and typesetters used actual italics (and bold).
text: I have not been able to confirm that anywhere, though.
text: The other answers are, of course, also correct.

sents: text: In some usage circles, titles and other things that would properly be set in italic are translated to uppercase instead.
text: For example: The Soandso Players will be performing THE TURN OF THE SCREW at the K---- Memorial Theater this August 30 th and 31 st .
text: I am told that this is a carryover from typewritten manuscripts, particularly stage plays and the like, where upper case is used to distinguish character names from dialogue.
