In this lesson you're going to learn how to move around and explore a level.
You can move with the [arrow keys].
You can reread all messages at any time with [Ctrl-P]. Also, press [Space] to
clear the --more-- prompts.
Found a staircase leading out of the dungeon.
There is a staircase leading out of the dungeon here.
You're doing great! Now, explore a bit until you reach the next blue square.
Move diagonally with the [number pad] (try Numlock on/off) [vi keys]
  Numpad:     7 8 9       vi-keys:    y k u
               \|/                     \|/

A quicker way to “run” through a corridor is to press [Shift] along with the
[number pad] (try Numlock on/off) or [vi keys].

When standing on a staircase leading downwards, you can enter the next level
with [>].

You climb downwards.
A new level! To begin with, head over to that door to the right.
Also, remember: You can reread old messages with [Ctrl-P].
There is a stone staircase leading up here.
You can open a closed door by walking into it.
You open the door.
There is an open door here.
You open the door.

Okay, then.
Note how you can move through shallow but not through deep water.

You open the door.
Found a stone staircase leading up.
There is an open door here.
When standing on a staircase leading upwards, you can enter the previous level
with [<].

What's this? To find out where you are, have a look at the minimap to the right
of the screen. You can enter the overmap view with [X] and then move the cursor
around to look around the level. You also can travel wherever your cursor is
pointing by pressing [.] or [Enter]. Press [Escape] to return to the normal
game mode.
There is a stone staircase leading down here.
Exploring manually can get tedious after a while, so you might want to let that
happen automatically. Try it by pressing [o].
Some dangerous ground is marked with exclusions. Autotravel will not lead you
into exclusions. Instead you will automatically stop.
However, autoexplore will move you safely around exclusions: so, you can safely
continue by pressing [o].
Autoexplore will stop when you first see items or dungeon features, like these
stairs. To travel directly to the stairs, you can press [X] to enter the map
overview, then [<] to move the cursor to the nearest up-stairs, and [Enter] to
go there.
Found an exit from the tutorial.
Congratulations! You've completed the first lesson!
To exit the tutorial, simply go up these stairs with [<]. Confirm the resulting
prompt with an uppercase [Y].
