- Open (or create) a Math object.
- Go to Tools -> Catalog (or “catalogue”, if you use the British version
).
- Click the Edit button.
- Below the “symbol picker” table, you will see something like this
- Code: Select all Expand viewCollapse view
Symbol |and |v|
Symbol set |Special |v|
Font | |v|
Subset |Mathematical Operators |v|
Typeface | |v|
Forget for a moment that these boxes are drop-down lists, delete the “and” and type the name for the new symbol (let's say, MySymbol). - Remember again that these boxes are drop-down lists and select a font containing your symbol, the “subset” from that font and, of course, pick from the table the character you need.
- If needed, and the font selected allows it, select a stile for the symbol (standard, bold, italic, bold-italic).
- Click the Add button.
Notice: You can also define a new “symbol set” to collect all your symbols.
