Split from Draw: Possible to create my own symbols?
Reason for split: Draw and Math are inherently different, which reflects in the approaches to creation of entities/groups. Also, the term "symbols" carry somewhat different meanings in the two.
i'm having simmilar problems myself... i have been tying to find a simple way to put "½" instead of the "1/2" or "1 over 2" that over doubles the height of the formula...
as well as symbols like "therefore" (∴) and "because" (∵)...
although i have found a way i can change (only change) the symbols they provide in the "Symbols" popup... but it doesn't have the symbols i'm looking for half the time...
also... before i forget... how can i imput just "%delta(x)=lbrace matrix{1#x=0##0#x<>0}" instead of having to put the "rbrace" (or some other bracket) at the end?

 Use the left and right keywords with the none token.
%delta(x)=left lbrace matrix{1#x=0##0#x<>0} right none
...or perhaps you wanted...
%delta(x)=left lbrace matrix{infinity#x=0##0#x<>0} right none

Thank you i did not find "left/right none" anywhere before
but still... my reason for posting in this was because i was wanting a way to imput symbols you do not carry at the moment...
either way thank you for erything soo far

here is one more good advice for using formulas in context! To make working with formulas easier, use the context menus, which can be called up with a right mouse click. This applies especially to the Commands window. This context menu contains all the commands that are found in the Selection window, and also operators, and so on, which can be inserted into your formula by mouseclick without having to key them into the Commands window.! _________________ Petrov
