+ Constructions (CIC) and with interactive theorem provers with procedural
+ proof languages (expecially Coq), getting started with Matita is relatively
+ easy. You just need to learn how to type Unicode symbols, how to browse
+ and search the library and how to author a proof script.</p><div class="sect1"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="unicode"></a>How to type Unicode symbols</h2></div></div></div><p>Unicode characters can be typed in several ways:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>Using the "Ctrl+Shift+Unicode code" standard Gnome shortcut. E.g. Ctrl+Shift+3a9 generates "Ω".</p></li><li class="listitem"><p>Typing the ligature "\name" where "name"
+ is a standard Unicode or LaTeX name for the character or an
+ ASCII art resembling the shape of the character. Pressing
+ "Alt+L" or Space or Enter just after the last character
+ of the name converts
+ the ligature to the Unicode symbol.
+ E.g. "\Delta" followed by Alt+L generates
+ "Δ", while pressing Alt-L after "=>" generates
+ "⇒"</p></li><li class="listitem"><p>Typing a symbol and rotating trough its equivalence class
+ with Alt-L. E.g. pressing Alt-L after an "l"
+ generates a "λ", while pressing Alt-L after an
+ "→" once generates "⇉" and pressing
+ Alt-L again generates "⇒".
+ </p></li></ul></div><p>
+ The comprehensive list of symbols names or shortcuts and their equivalence
+ classes is available clicking on the "TeX/UTF-8 table" item
+ of the "View" menu.
+ </p><p>
+ There is a memory mechanism related to equivalence classes that
+ remembers your last choice, making it the default one. For example,
+ if you use "_" to generate "⎻"
+ (that is the third choice, after "⎽" and "⎼"),
+ the next time you type Alt-L
+ after "_" you immediately get "⎻".
