What symbols can I use, and how do I enter them?

The following is a list of characters that can be used

  • ✰ Any alphabetical character from A all the way to Z
  • ✰ The conditional operator ( → ) can be inserted if you press the shift key and the > key at the same time
  • ✰ The bi-conditional operator ( ↔ ) can be inserted if you press the shift key and the < key at the same time
  • ✰ The disjunction operator ( ∨ ) can be inserted if you press the shift key and the v key at the same time
  • ✰ The conjunction operator ( & ) can be inserted as you normally would type an ampersand
  • ✰ The negation operator ( - ) can be inserted as you normally would type a dash
  • ✰ Opening ( and closing ) parentheses can be inserted as you normally would type them
  • ✰ Spaces!

The following list, though not exhaustive, cannot be entered

  • ☹ Numerals ie 1234567890
  • ☹ Punctuation like , . or even ?
  • ☹ Brackets like { or [
  • ☹ Probably some other stuff
