In Hacknet the player applies terminal syntax to the current problem. ## At a glance ![Hacknet: a quick command reference beside the terminal](https://gamemechanics.pro/images/mechanics/interface-hacknet-00.webp) [Hacknet](https://store.steampowered.com/app/365450/) · © Team Fractal Alligator / Fellow Traveller.

Quick Reference Guide explains the commands - Separate command knowledge from typing speed when testing understanding. - [Hacknet](https://store.steampowered.com/app/365450/) ## How it works The same input creates different tasks depending on the prompts and mental load. ## Variants ### Variants and applications - Repeat the disappeared pattern. Action: A sequence, chord or pattern is first shown, then entered from memory. Applications: Memory play, procedure teaching, musical echo. Conditions: Pattern length, delay, and replay availability vary. Equipment: Regular keyboard. - Transform the pattern in your mind. Action: Enter the shown material in reverse order, with an offset or according to a conditional code. Application: Logic puzzle, melody transposition, encryption problem. Conditions: The transformation rule must be unambiguous. Equipment: A regular keyboard. - Find an unknown match. Action: Experiment with the keys and deduce a pattern based on the system's response. Application: Unknown panel, alien device, learning through exploration. Conditions: Sufficient feedback is needed for the solution to be deducible. Equipment: Regular keyboard. - React to the selected sign. Action: The command depends only on one of several properties of the tooltip. Application: Click on the color, ignoring the written word; sort dispatcher signals. Conditions: Feature conflict is a cognitive rule on top of a simple press. Equipment: Regular keyboard. - Switch rule. Action: The same stimulus requires different responses under the current condition. Application: Varying operator instructions, flexibility task, changing roles in training. Conditions: The current rule must be known or explicitly specified as a memory task. Equipment: Regular keyboard. - Combine two tasks. Action: Type text and simultaneously serve another thread of actions. Application: Correspondence while controlling the ship, music part plus alarms. Conditions: You can separately adjust the difficulty and tempo of each thread. Equipment: Regular keyboard. - Select a signal from interference. Action: Click only on significant events, ignoring similar false ones. Application: Radar operation, rhythmic track with distracting notes, searching for the necessary letters. Conditions: Distinguish between selection error, omission and time error. Equipment: Regular keyboard. - Master the scheme with decreasing hints. Action: Hints gradually disappear, but the location and rules are preserved. Application: Touch typing, teaching hot keys, mastering the musical layout. Conditions: The speed of removing hints should be based on the observed success of the user. Equipment: A regular keyboard. ## Context and limits Author's working classification for designing games and interactions. Options can overlap and combine; the list is not a generally accepted standard or proven exhaustive list. Application examples are conditional unless a specific verifiable observation is indicated nearby.
