I am practising '[ and '], and I cannot see the difference.
How can you highlight the positions of the marks?

Use ` instead to get the exact to the start change/yank mark, start a visual block and then jump to the end change/yank mark followed by any lower case letter....
With a mark it just takes you to the line, not to the exact character.

What do you call the punctuation marks { and } ?
Braces? Curly brackets? Something else?

[ and ] are brackets or square brackets....
Curly braces.
"Braces" -- to me, "brackets" refers to [ and ] .
Curly Braces
" Braces ".
I write or type them when possible.
Curly brackets"
"Brackets"
I don't know, so I try to avoid calling them anything .

Usually, free pdf writers/editors include a watermark unless you buy the product .
If you mean registration watermarks, either you have to crack the software (which I am not telling you to do) or you have to buy it .

Might you be able to simply replace any single quotes with double quotes in your file?
... .
S/\'\(.*\)\'/"\1"/

You need to put round brackets around the part of the expression you wish to capture .

Just curious how is the .NET 4.0 CLR world going to call methods ending in question marks and exclamations? What will the syntax look like calling from C# or VB.NET?

The CLR allows a much larger set of characters to be included in type and member names than is typically available to most languages (such as C# and VB.... .
At a CLR level there is simply no problem.
I think you have to differentiate the cases a bit here .

Take it as a byte array, and convert it to a displayable... .
Note that saving the encrypted result in a string will possibly result in loss of the data, so don't do that .

Ran across this line of code:
FormsAuth = formsAuth ?? new FormsAuthenticationWrapper();
What do the two question marks mean, is it some kind of ternary operator? It's hard to look up in Google.

Answer Snippets (Read the full thread at stackoverflow):
FormsAuth = formsAuth ?? new FormsAuthenticationWrapper();
expands to:
FormsAuth = formsAuth != null ? formsAuth : new FormsAuthenticationWrapper();
which further expands... .
It's the null coalescing operator, and quite like the ternary (immediate-if) operator .
