Dear all,
I have two problems with formula editor in OOOWriter.
1. How to write down the formula for integral with lower and upper limit? I'm trying something like "from <0> to <t> int kdx", but it gives questions marks.
2. How to write down formula for chemical ions? For example, H^(+) ? It works fine if I make H^+1, but gives question marks if I put H^+

Sorry, if these questions have been raised already, but I didn't find it by search.
All the best.

Looks like problem one has been solved by using "stack" command, e.g.:

stack { t_max # int { } # t_min } exp (-k_1 cdot t) dt

Problem #2 still isn't solved

1) int from {0} to {infinity} %GAMMA(x) dx

2) Math is not well suited for chemical formulas, but this one you can do without too much trouble:

• H^"+"
  or
  "H"^"+"
  or
  H^{{}+{}}

Great, thank you! I tried it, everything is working! Thank you very much!

Alternatives for (1):

int_0^{t} ~k dx

int rsup {t} rsub {0} ~k dx

both avoid the 0 and t being directly below and over the integral sign respectively, but the 0 is too far to the right. An old problem it seems:

I also tried with OOoLatex, but the limits appear full size – not sure what's wrong there.

You can use the from/to keywords, but start with the integral:
int from 0 to t kdx

It keeps the logic, so it's easier to read than the stack/sub/sup modifiers. It positions the limits above/below the integral sign (I can't see any way to make the limits appear to the right, like rsup/rsub does).

Try this also:
"He" lsup{4}lsub{2}
useful for isotopes

See that font and extension described here: Automatic ligature support though graphite fonts.

Do ypu know probably how to replace keyword from input string? i use Jquery
