We recommend having Archipelago's Text Client open on the side to keep track of what items you receive and send.
APDOOM has in-game messages,
but they disappear quickly and there's no reasonable way to check your message history in-game.
### Hinting
To hint from in-game, use the chat (Default key: 'T'). Hinting from Heretic can be difficult because names are rather long and contain special characters. For example:
```
!hint The River of Fire (E2M3) - Green key
```
The game has a hint helper implemented, where you can simply type this:
```
!hint e2m3 green
```
For this to work, include the map short name (`E1M1`), followed by one of the keywords: `map`, `blue`, `yellow`, `green`.
## Auto-Tracking
APDOOM has a functional map tracker integrated into the level select screen.
It tells you which levels you have unlocked, which keys you have for each level, which levels have been completed,
and how many of the checks you have completed in each level.
