Description agpallitit 2003-02-17 21:16:54 UTC
Would it be possible to change the placeholder from <?> to {?}. That would 
simplify things like writing fractions and other things in need of grouping.
Comment 1 thomas.lange 2003-02-18 08:13:21 UTC
Do you use the selection box?

If so, since you probably already use the mouse a lot, how about 
double clicking on the place-holders in the graphic display?
This will select the text for the place-holder in the command window.
Does that suit you?

Did you notice that you can travel between those markers by pressing 
(I think) F2 and shift-F2 in the command window?

If this suits your needs just put a response in this bug and I will 
close it, otherwise I'll pass it on for someone to decide abouzt this.
Though I have to say that the chances are it won't be changed because 
since it is already used this way a long time, the import/export of 
already existing documents with formulas would need to be changed 
Comment 2 agpallitit 2003-02-18 09:24:02 UTC
Personally i don't use the selection box very often, I find it much
faster to "code" the formulas by hand. But as physics and math
teacher, I have to teach my pupils how to use the formula editor, and
they almost always use the mouse and the selection box, and my reason
for suggesting the change from <?> to {?} is simply at matter of
convenience for selection box-users, since I find that the <?> is very
rarely substituted by a single number or letter, but by things that
need grouping anyway. And e.g. 1 and {1} is already treated the same
way by the editor today.

Double-clicking placeholders in the graphic display doesn't always
work the way you would expect, e.g. if you want to add the fractions
1/n and 1/m to get (m-n)/mn, you have to type {m-n} in the
placeholder, not just m-n as you reasonably could expect. That kind of
problems would be resolved by the suggested change.

I'm not really sure I understand how and why this will affect old
formulae, but this is not the right forum for discussing taht, I think.

How about replacing <?> by {<?>} in the selection menu and the 
context menu of the command window?

Would that be OK?

It can also be considered to replace <?> by sth. like {X}. Of course 
then no placeholder icon will be displayes but only an X.
Any other suggestions?

I still would need approval for the change though.

About old formulas:
If you like having {?} work like <?> (and still displaying the 
placeholder icon) it will effect old formulas since when loading <?> 
it has to be translated into {?} while loading. Also the parser needs 
to be change.
The main issue is if you like to have {?} being displayed as the 
placeholder icon. 
To replace the text <?> that gets inserted in the command window by 
another one (without further special effects) is a simple matter.
Comment 4 agpallitit 2003-02-18 20:45:00 UTC
Replacing <?> with {<?>} would be OK, that would surely solve the 
"fraction problem" I mentioned earlier. (And it might please former 
MathType/ Equation editor - users that "boxes" behave the way they're 
used to ;-))

Although I prefer keeping symbols as simple as possible, I think 
replacing <?> with {X} might be confusing, if it means that no 
placeholder will be displayed.
