If you're looking for help on how to use the program, just press
? while its running. This mess will not help you.
Urwid aint my speed. Hell, making complex, UI-oriented programs
aint my speed. So some of this code is pretty messy. I stand by
it though, and it seems to be working rather well.
Most of the functionality is crammed in the App() class. Key
handling is found in the other subclasses for urwid widgets.
An instantiation of App() is casted as `app` globally and
the keypress methods will call into this global `app` object.
There are few additional functions that are defined outside
of the App class. They are delegated to the very bottom of
this file.
Please mail me (~desvox) for feedback and for any of your
"OH MY GOD WHY WOULD YOU DO THIS"'s or "PEP8 IS A THING"'s.

"numeric post referencing, ala >>3 for the third reply.",
"[red: Whitespace]",

"own. Adding them yourself can cause your posts to look very strange. You can "
"always edit your posts after submitting them if you do this by accident, as "
"long as you are not anonymous.",
"In previous versions of BBJ, linebreaks were joined into sentences if they "
"occured in the same paragraph, however this confused many users and has been "
"reverted to just use whatever was submitted, as-is.",
"[red: Colors, Bold, Underline & Expressions]",
"You can use [rainbow: rainbow], [red: red], [yellow: yellow], [green: green], "
"[blue: blue], [cyan: cyan], [magenta: and magenta], [dim: dim], **bold**, and __underline__ "
"inside of your posts. \**bold works like this\**, \__and underlines like this\__. "
"You can escape these expressions \\\**like this\\\**. They can span up to the full width "
"of the same line. They are best used on shorter phrases. "
"However, you can use a different syntax for it, which is also required to use "
"colors: these expressions \[bold: look like this] and have less restrictions.",
"The colon and the space following it are important. When you use these "
"expressions, the __first__ space is not part of the content, but any characters, "
"including spaces, that follow it are included in the body. The formatting will "
"apply until the closing ]. You can escape such an expression \\\[cyan: like this] "
"and can also \\[blue: escape \\\] other closing brackets] inside of it. Only "
"closing brackets need to be escaped within an expression. Any backslashes used "
"for escaping will not show in the body unless you use two slashes.",
"This peculiar syntax elimiates false positives. You never have to escape [normal] "
"brackets when using the board. Only expressions with **valid and defined** directives "
"will be affected. [so: this is totally valid and requires no escapes] because 'so' is "
"not a directive. [red this will pass too] because the colon is missing.",
"The following directives may be used in this form: red, yellow, green, blue, cyan, "
"magenta, bold, underline, dim, and rainbow. Nesting expressions into eachother will "
"override the parent directives until the innermost expression closes. Thus, nesting "
"is valid but doesn't produce layered results on the command line client.",
"[red: Quotes & Greentext]",
"You can refer to a post number using two angle brackets pointing into a number. >>432 "
"like this. You can color a whole line green by proceeding it with a '>'. Note that "
"this violates the sentence structure outlined in the **Whitespace** section above, "
"so you may introduce >greentext without splicing into seperate paragraphs. The '>' "
"must be the first character on the line with no whitespace before it.\n>it looks like this\n"
"and the paragraph doesnt have to break on either side. The formatter is smart enough to "
"differentiate between >>greentext with multiple arrows and numeric quotes (outlined below) "
"given that the text doesn't start with any numbers.",
"When using numeric quotes, they are highlighted and the author's name will show "
"next to them in the thread. You can press enter when focused on a message to view "
