Numbering Equations

users
#1

In LibreOffiice 3.3 Math Guide (0700MG33-MathGuide3.3.odt), on p. 14, the
following is written:

*Numbering equations*

Equation numbering is one of LibreOffice Math’s best hidden features. The
steps are simple, but obscure:

   1.

   Start a new line.
   2.

   Type *fn* and then press *F3*.

The *fn* is replaced by a numbered formula:

  [[equation: E = mc2] (2)

()

Now you can double-click on the formula to edit it. For example, here is
the Riemann Zeta function:
[equation: [Rieman Zeta Function] (3)

You can reference an equation (“as shown in Equation (2)”) with these steps:

   1.

   Choose *Insert > Cross-reference* from the menu bar.
   2.

   On the *Cross-references* tab (Figure 17), under *Type*, select *Text*.
   3.

   Under *Selection*, select the equation number.
   4.

   Under *Format*, select *Reference*.

It's possible to do what you're trying to do without the F3 key. Go to the Edit menu and select AutoText. You should see a list of categories. Expand the one called Standard. If you scroll down the resulting list, you should see the entry 'Formula Numbering'. Select it and then click on the Insert button. Your equation should appear.

Does this work for you?

I think what you may be doing (understandably) is to try this in a Math document - and I cannot see how it works there. Instead, it works as described in a text (Writer) document. Indeed, I notice that the version of the Math Guide for LibreOffice version 3.5 has corrected "Equation numbering is one of LibreOffice Math's best hidden features" to read "Equation numbering is one of Writer's best hidden features".

In a text document, in a new paragraph or after a space, type "fn" and press F3. A table with a single row of two columns appears, containing a dummy equation and the required number (as a field). You need only to double-click the equation to open the Math window at the bottom of the window, where you can remove the dummy equation's definition and replace it with your own.

I trust this helps.

Dear Robert,

Thank you very much for your reply. Now I know how to bypass the typing of
fn and the pressing of F3.

I typed fn in the Equation Editor and I found just fn in the document.
Beside the fn in the document, I pressed F3, and I got an onscreen message:

AutoText for Shortcut " not found.

So I think that something is missing on my computer, or at least on my
LibreOffice.

I have some more questions, which I hope I can post here in the coming days.

Sincerely,

Taang Zomi

The *fn* is replaced by a numbered formula:

When I typed fn and pressed F3, nothing happened. In the document the fn I
typed appeared, not the desired result.

I do not know whether my F3 key did not work.

Can somebody kindly explain in step-by-step detail how to number
equations.

If you see that message, then F3 is working. You're not supposed to type fn in the equation editor. Just type it in the document itself as regular text and then (with the cursor immediately to the right of 'fn') press F3. As mentioned in another response, make sure that you're doing this in a Writer document.

Dear Brian,

Thank you very much for your reply.

Recently I became interested in linguistic phonology, and so I tried
LibreOffice Math. I rarely tried Math before. So I am a Math novice.

I guide I used was LibreOffice 3.3 Math, which was a bit old. Now I
downloaded LibreOffice 3.5.5 Math Guide.

The typing of fn and the pressing of F3 yields an onscreen message:

AutoText for Shortcut " not found.

Something seems to be missing on my computer. Perhaps I need to re-install
LibreOffice 3.6.4, which I am using?

I have some more questions which I hope I can post here in the near future.

Sincerely,

No, I suspect that you are simply not following the advice given. *Don't* start a Math document. *Don't* use Insert | Object >

Formula. Instead, forget about Math for the moment! In a text

(Writer) document, type "fn" in a new paragraph and press F3. You will see the dummy numbered equation. Now double-click the equation: this will automatically open the Math sub-window and you can replace the dummy equation's definition by your own.

Thank you very much for your reply.

I just started a new Writer document, typed fn and then pressed F3, and
got the same message:

What version of LibreOffice are you using?
       Use Ctrl+F3 to open the AutoText dialog. Open the Standard folder in the Name window. Look for "Formula Numbering" in this list.
      I checked my LO versions. LO 3.5.7, 3.6.5, and 4.0.0.2 have it. I don't know when LO started putting this AutoText in the AutoText dialog, so if you have a version earlier than I do, you may not have it.

I don't understand. Did you type a space (or anything else) after the "fn"? You mustn't do that!

Brian Barker

I hesitate to quibble, but this is unlikely to be the problem, I think. If the particular AutoText were missing, the error message should be "AutoText for Shortcut 'fn' not found", whereas it is actually reported as "AutoText for Shortcut '' not found" - in other words, AutoText seems to be failing to pick up the shortcut "fn" in the first place.

Hi :slight_smile:
Is the fn a single key on the keyboard like the Ctrl or Alt keys?

Tom :slight_smile:

Er, no: you get the result "fn" using a very crafty technique, sometimes known as "multiple keying".

o First you press the "f" key very briefly.
o Then you take your finger away from the "f" key and briefly press the "n" key instead.
o Now you will see the required result "fn" in your document.

I trust this helps.

Dear Dan,

I use LibreOffice 3.6.4 (Build ID: 2ef5aff).

Yes, Ctrl + Fn works.

I typed a space after the "fn", and typed no space after the "fn". I got
the same result:
AutoText for Shortcut " not found.

Then something strange is happening for you that doesn't generally.

I'm running out of ideas. Here's another couple of things to try:

o Open the AutoText dialogue (e.g. by pressing Ctrl+F3 as has been discussed).
o Expand the Standard group.
o Does "Formula Numbering" appear in the list (as it should)?
o If you select it, does "FN" appear in the Shortcut box (as it should)?
o If not, someone has customised your set-up and upset the facility.

o At the top of the AutoText dialogue, ensure "Display remainder of name as suggestion while typing".
o Close the AutoText dialogue.
o In the text (Writer) document, type "For".
o Does a small note window saying "Formula Numbering" appear?
o Whilst the small window is displayed, press Enter.
o Does the dummy numbered equation now appear?

I did all you said above, and I got all the results.

Dear Tom.

My keyboard does not have "fn"key as a single key.

Sincerely,

Taang Zomi

Good-oh!

The second suggestion is an effective workaround for you, then: typing F, o, r, Enter is hardly any longer than f, n, F3 would have been.
