1. If I want two or more symbols to appear together (for example √ or →∞), I can't just click on the two symbols. The second symbol replaces the first, unless I click back in the text box in between. Is is possible to have the second symbol click not replace the first one?
seconded

at present, the symbol is inserted and highlighted, it would be easier if it was inserted and then the cursor was placed after it

I'm thirding that suggestion. It's not too hard to work around the problem. Just hit the right arrow key after clicking a symbol. But if it's easy to change, then I think we should.

I noticed the posting area tends to run over on the righthand side with the typical browser window size I use in both Safari and Firefox, while there's an awful lot of wasted space on the left. Perhaps the posting area could be centered within the column rather than having a fixed left margin.

One other suggestion would be to use a different font for the Greek letters. With the current font, alpha looks like a lowercase A and pi looks like a lowercase N, which has caused confusion in the past.

Greg, do you think you can add to the list? I use that symbol more than any of the ones that are on that list now. It's used for Cartesian products and in phrases like "mn matrix". The symbol would be very useful too. If you don't want to add another line of characters, then just remove one or two of the lesser Greek letters.

I wouldn't use α or χ, because they don't look enough like ##\alpha## and ##\chi##, and I always LaTeX the symbols ∂ ∫ Ʃ ∏, so I don't find them useful either. I don't know if other people do.

I don't offhand see it as an HTML entity. That isn't chi?

Here's a couple of symbols that are missing with their html equivalents:

φ: φ
: ×
: ·
∈: ∈

And, if only to please Mike: ;)
ξ: ξ

i use ∂ ∫ and ∑ a lot (though i can type them on my mac keyboard, so i don't use the box)

can we please have φ (the box's ∅ looks terrible in equations ), and ∫, and ∇ ?

∅ is the empty set.

I agree that φ would be useful (occasionally).



I think I use each of these four symbols more than all the the others combined:

≤ → ℝ

These ones are all pretty useful too (the is not currently on the list)

≥ ℂ ∞ ≈ ≠ ε δ ψ ∅

I also use these occasionally:

β γ ρ θ λ (I would mention φ here, if it had been on the list).

I don't think I ever use any of the others.

Hm...is there an ##\hbar##?

tiny-tim, the "Learning LaTeX" link in your signature could use an update.

looks ok to me
and the Learning Latex sticky
actually, with the new box, i hardly ever use my signature
btw, is the box invisible on some devices (eg phones)?

You're linking to the old sticky (which is no longer a sticky), but at least it contains a link to the new one. I just thought that you might want to link directly to the new one, but you can of course link to whatever you want to.

here's a typical thread where ∅ looks horrible
Quote Quote by physics kiddy View Post
1. The problem statement, all variables and given/known data

Prove that:
tan^2∅/tan∅ - 1 + cot^2∅/cot∅ - 1 = 1 + sec∅cosec∅

2. Relevant equations



3. The attempt at a solution

I have solved the question taking tan∅ = sin∅/cos∅.
But I want to solve it some other way.
(i've taken to typing ψ instead of ∅ )
can we please have φ ?

Well, yes, but that's like saying that the word "fo∅l" looks weird when one of the o's is replaced by the empty set symbol. It's not a phi, and to try to use it as a phi is quite bizarre.

φ is one of the more useful greek letters, so I wouldn't mind having it added to the list. It's not as useful as though.

Do people really use ∴and ∠ ?
