Can we have an Omega smiley?

[apelly]

At risk of being "one of those guys"; it looks to me like smileys in the forum are a little icon in some folder with some associated free text. When rendering, the icon is substituted for the text.

If I'm right, a simple smiley that inserts would serve two functions, and be easy to implement. Primarily it'd prompt people to remember that slash dollar are the escape characters to initiate \$\LaTeX\$, but it's also a handy short cut.

At first this didn't make sense, having symbols for emoticons, but now I get that it could be useful.
If someone has a list of useful symbols in the appropriate size then I can add them.
Omega would be :ohms:

[apelly]

I was actually thinking of functionality similar to the url button; it inserts text that you can then edit as desired. It saves a bit of typing, but more importantly it shows the syntax if you've forgotten it. In my imagination an ohms button would literally insert the characters ""

I referred to smileys, because they appear to be a shortcut to insert some text and are apparently not too hard to create.

I would use latex a lot more if I didn't have to re-research how to use it every time.

Anyway, I also see no reason to have a static gif shaped like omega. It's only useful if it fits in with the text.

Do the Alt codes work in the forum software, I think I'tried them before and they wouldn't.

Let's try Ohms: Alt234

Nah

Testing:

\$\omega\$
\$\Delta\$

Another try from this list
http://www.planetquark.com/images/library/tips/Special_CharacterShortcuts_v.1.2.pdf

WINDOWS|To access the desired glyph, first turn on NUM LOCK. Then hold down the ALT key while using the numeric keypad to enter the the four-digit number shown.
Release the NUM LOCK key when finished. So, to access the n with a tilde accent, press NUM LOCK, then hold ALT
and key 0241. Hit the NUM LOCK key again to release it.

Nah, needs someone smarter than me.

I don't have any numeric keys on this keyboard, but copy and paste seems to work. I wonder if it has any browser or OS dependencies though. Does everybody else see the 4 symbols above?

Okay, they all worked in preview, but after posting the "omega" is a question mark. Which is weird.

Testing:

\$\omega\$
\$\Delta\$

Nice, isn't it?
Two great resources:
http://meta.math.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference
http://detexify.kirelabs.org/classify.html

The second one lets you draw that character you want, then gives you its name.

Not really.  Posting will go through a bit more processing than Preview.  Obviously, there is something special happening when you 'Post'.

[Brumby]

Testing:

\$\omega\$
\$\Delta\$

Cute

\$\Omega\$  gives you: 
\$\omega\$  gives you:  \$\omega\$
\$\Delta\$  gives you:  \$\Delta\$

[rdl]

I see the same thing before and after "gives you:"

backslash dollar sign backslash Omega backslash dollar sign

[Brumby]

Does Dave's test show up ok?

[Brumby]

Is this any different?

\$\Omega\$
  gives you:
 

\$\omega\$
  gives you:
  \$\omega\$

\$\Delta\$
  gives you:
  \$\Delta\$

[rdl]

Nope, looks the same. Dave's does too.

[Brumby]

Then it's going to be something to do with your particular environment.

I'm not familiar with the in's and out's - but there will be someone here that will know.

[rdl]

Then it's going to be something to do with your particular environment.

It was. I had to enable javascript from some place called mathjax.org
I don't remember seeing that here before, only eevblog.com and supplyframe.com

[Brumby]

Thought it might be something like that - but I didn't really know.

So to answer your question - Yes


What is interesting is that there is a time delay - I think it has something to do with the Australian Post Office

I doubt it.

If it was, there would be a fee or charge of some sort...

To add these I will need gif image files of the actual symbols in the appropriate size. I can't seem to find a handy list, even after downloading the entire build and looking at the image file directories 

[Brumby]

What pixel size are you looking for?

[IanB]

Seemingly it needs to be about 12 pixels high. Here's a test example (attached) of the ohms symbol. It's not the right quality, but it could be used to test the concept.

Something like this, I guess:

    R = 30

\$\alpha\$    alpha     \$\Alpha\$    Alpha

They are the same as the Roman letter, they do not need special handling...

[Brumby]

Yeah ... but it spoils the logic.
