Action: Use only certain symbols or avoid specified ones. Application: Lipogram, damaged terminal, spells from available runes. Conditions: The final text or each event is checked; these are different conditions. Equipment: Regular keyboard. <a id=\"variant-k073\"></a>\n- Word formation according to the rule. Action: Create words of the desired length, category, ending or structure. Application: Word battle, educational quiz, selection of a recipe based on the properties of a word. Conditions: A dictionary or clear, testable grammar is needed. Equipment: A regular keyboard. <a id=\"variant-k074\"></a>\n- String conversion. Action: Reverse typing, encrypt, replace or rearrange characters. Applications: Decryption, mirror messages, logic puzzles. Conditions: For international text, consider compound characters and graphemes. Equipment: Regular keyboard. <a id=\"variant-k075\"></a>\n- Case and punctuation as meaning. Action: Different forms of notation indicate different actions or quality of the result. Application: Increasing the power of a spell with case, syntactic tasks, precise command entry. Conditions: The rule must retain meaning in supported languages. Equipment: A regular keyboard. <a id=\"variant-k076\"></a>\n- Time limit for text. Action: Complete a word, phrase or message before the deadline. Application: Save a character by typing a command, high-speed correspondence, emergency protocol. Conditions: The length and language of the text must be taken into account when setting the time. Equipment: A regular keyboard. <a id=\"variant-k077\"></a>\n- Consequences of typos. Action: An error changes the world: it causes damage, creates interference or distorts the command. Application: Unstable spells, a noisy communication channel, operator simulation. Conditions: The tolerance for errors and the possibility of correction are set explicitly. Equipment: A regular keyboard. <a id=\"variant-k078\"></a>\n- Correction as a resource. Action: Backspace, replacement and cancellation are limited, paid or provide a separate benefit. Application: Editing puzzle, restoration of damaged text, proofreader fight. Conditions: Do not mix the price of correction with the requirements for the input method. Equipment: Regular keyboard. <a id=\"variant-k079\"></a>\n- Ambiguity and autocompletion. Action: Select from multiple completions, expand a shortcut, or accept a hint. Application: Command palette, word prediction, minimum number of characters game. Conditions: Hints must be accessible from the keyboard and show the selected option. Equipment: Regular keyboard. <a id=\"variant-k080\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
