For a couple of commands, Typst offers shorthand notations (see, i.e., here for arrow symbols).
For example, capital letters in math.bb(A) can be written by repeating the same letter twice (AA, BB, etc. for all capital letters)

Here's a list of arrows that also have shorthands.
| Longhand | Shorthand |
| gt | > |
| lt | < |
| gt.eq | >= |
| lt.eq | <= |
| lt.double | << |
| lt.triple | <<< |
| gt.double | >> |
| gt.triple | >>> |
| arrow.r | -> |
| arrow.r.long | --> |
| arrow.r.bar | |-> |
| arrow.r.tail | >-> |
| arrow.r.twohead | ->> |
| arrow.l | <- |
| arrow.l.long | <-- |
| arrow.l.tail | <-< |
| arrow.l.twohead | <<- |
| arrow.l.r | <-> * |
| arrow.l.r.long | <--> |
| arrow.r.squiggly | ~> |
| arrow.r.long.squiggly| ~~> |
| arrow.l.squiggly | <~ |
| arrow.l.long.squiggly| <~~ |
| arrow.r.double | => |
| arrow.r.double.bar | |=> |
| arrow.r.double.long | ==> |
| arrow.l.double.long | <== |
| arrow.l.r.double | <=> |
| arrow.l.r.double.long| <==> |
| bracket.l.double | [| † |
| bracket.r.double | |] † |
| bar.double | || * |
* Hieroglyphic actually suggests the shorthands for arrow.l.r and bar.double
† bracket.r.double and bracket.l.double are deprecated, instead use bracket.r.stroked and bracket.l.stroked
