Yeah, I think it's a relic from the teletype days. A teletype had no screen, it was basically a printer connected to a computer. All output was immediately printed out. So you could get a letter like è by entering an e, then a backspace code, then `, causing the ` to appear over the e. When video screens started appearing, they lost the ability to display more than one character on top of each other like that, but the ASCII standard had already been developed and programmers found a use for characters like ` in programming languages and command-line environments.

When I first started using the Internet, I used ` as apostrophe. I remember typing stuff in DOS Edit and being annoyed that I had to press it twice. Someone said something like "you play too much pokemon, our keyboards have ' keys" and I looked and sure enough there was one, so I used that. (Not sure what that has to do with Pokémon, but anyway...)

Yeah, I've also seen people write Poke`mon and stuff like that, which is annoying

It's Pokémon, not Pokemon or Poke`mon.

The diacritic omission that really pisses me off is "uber". The word is über, with an umlaut. Considering that ü can be substituted "ue" in German if you can't type an umlaut, there is no excuse for "uber" becuse you can type "ueber" if you can't get the ü or are too lazy.

Not many people know how to type extended characters like é or that you can use ue in place of ü, though.

And I just type Pocket Monsters. I'm a freak, I know. I still remember trying to code things on the C64.

Hmmm...the worst thing about the C64 keyboards were that they had only two arrow keys. You had to do shift-right for left, and shift-down for up. On the other hand, the screen editor allowed you to change a program line simply by moving the cursor up to the line, entering the change and hitting return. On Apple IIs and most other contemporary computers, you had to retype the whole line.

That... makes no sense, whatsoever. Come on.

I followed Kles suggestion. Did I do it right?

If you look at ASCII, you'll notice that before the numbers is the shift+number symbols.
On the c64, " was shift+2. Let's see, so what comes after ! (shift+1) in ascii?

Also, on the c128, they fixed the arrow keys, so there were 4, one for each direction. Granted they were on the topmost row of keys, and the said dual-directional keys still were on the keyboard, but that's not the point.

Oddly, enough, the Commodores didn't use ASCII. They used PETSCII and Screen codes.

PETSCII is ASCII-based but has several differences, the biggest one being that the uppercase and lowercase letters were reversed, so lowercase was 65-90 and uppercase was 97-122. Some other symbols were different, such as \ was a British pound and ^ was an up arrow. 0-31 and 128-159 were control codes radically different from those in standard ASCII. Backspace was 20, for instance. Codes 160-191 were graphics symbols like line-drawing characters and such, and 192-255 were just repeats of various lower characters.

Screen codes were used by the video chip and some word processors. Reverse video characters had their own set of Screen codes which were 128-255, and all the printable characters are crammed into 0-127 with no control codes. The lowercase alphabet is codes 1-26 and uppercase is 65-90.

Not only that, the Commodores had two character sets, and both PETSCII and Screen codes could be referring to either set, plus you could make custom character sets in RAM. One set is as described above and the other only has uppercase letters and additional graphics characters including card suits.

Basically, if there were two ways of doing anything, IBM and clones did it one way and Commodore was the exact opposite.
